Annaklin Collapsible Containers Review: Months of Daily Use in a Small RV

I bought the Annaklin 8-pack collapsible silicone food storage containers in spring 2025, the same week I bought the CAROTE 19-piece detachable handle cookware set. That was not a coincidence. In our 2019 Class C motorhome, 25 feet long, the narrow galley drawer was already spoken for, and the one overhead cabinet had to hold everything else. Leftovers in the 6 cubic foot fridge were a daily problem. Round bowls slid, tall stacks tipped, and every extra inch of height cost me something else I needed. I wanted containers that could hold chili on Tuesday and then fold down to almost nothing on Wednesday. The Annaklin set was my attempt to solve that without adding another rigid box to the rig.

We have traveled part of every year since I retired in 2021, mostly the Pacific Northwest and the Southwest in winter. I cook almost every day in that galley. Ray, my husband, handles the grill and the campfire. The containers became the answer to a smaller question: where does the leftover chili go, and where does the container go when it is empty? Months later, I have a clear answer. They are useful, not flawless, and they have earned a place in the overhead cabinet.

How I've Used It

I keep the full Annaklin set in the overhead cabinet above the galley counter. The four sizes are 11.8 ounces, 16.9 ounces, 27 ounces and 40.5 ounces. In practice, the 40.5 ounce container holds a lunch-sized portion of chili or stew. The 27 ounce one is my rice and pasta container. The 16.9 ounce ones take berries, cut melon or a handful of grapes. The 11.8 ounce ones are for dressing, nuts, sliced olives or a few leftover meatballs. I use the rectangular ones for leftovers because they fit the fridge shelf better, and the round ones for fruit. The set has eight containers total, and I have never wished for a ninth.

The routine is simple. I fill a container, press the lid down, and check that all four snap buckles have caught. Then it goes into the 6 cubic foot fridge or the freezer. At home in Salem, I run the pieces through the dishwasher on the top rack. On the road, I wash them by hand in the sink with a small amount of water, because our tank space is limited and I do not want to use half of it on dishes. The silicone body flexes enough that a sponge reaches the corners. The plastic lid is the part that needs attention, especially around the seal ring. I dry the seal ring with a corner of the towel before I put the lid back on. If I stack a wet lid on a dry container, the ring can pick up lint from the shelf. I keep a small bottle brush in the galley drawer for the corners of the 11.8 ounce containers. A regular sponge is too fat for those.

The containers also solve the open bag problem. A bag of frozen peas or a half bag of shredded cheese goes into a container instead of rolling around the fridge. That sounds small until you have spent ten minutes looking for the cheese behind the milk. I also use them for prepped ingredients before they hit the cooktop. Chopped onions and peppers for the Blackstone griddle go into a 16.9 ounce container. Sliced mushrooms go into another. If Ray is making pancakes outside, I can carry batter out in the 27 ounce container and bring the empty back without dirtying a bowl. On day trips to a lake, I pack sandwiches and cut fruit in the larger containers. They are not a cooler, but they keep the car from filling with loose plastic bags.

The Space Math in a 25 Foot Rig

The reason I bought collapsible containers instead of more rigid ones is height. The listing gives the set's dimensions as 11.02 inches long, 8.46 inches wide and 4.53 inches high. The total capacity is 192.4 fluid ounces across the eight pieces. When the containers are empty and collapsed, the set takes up roughly half the space, which is the number the listing gives. In a 25 foot motorhome, half an overhead cabinet is not a small thing. That is where I keep the coffee filters, the extra paper towels and the good knives. The Annaklin set lives on the same shelf without crowding them.

I stack the collapsed pieces in two short piles. The lids go in a small mesh bag beside them so I am not digging for a match at dinner. When the containers are full, they stack in the fridge because the rectangular pieces have lids that sit level enough for another container on top. The round pieces are less efficient in the fridge, but they are easier to eat from at the picnic table. The trade is worth it. I would rather have two shapes that do different jobs than eight containers that all fit the same way.

The overhead cabinet is shallow. A rigid quart container would fit, but four of them would not. The collapsed Annaklin pieces fit in the same footprint as a folded dish towel. When I need one, I pull it out, pop it open, and the cabinet does not turn into a game of Tetris. That is the practical test I use now: can I get the thing out without unloading the cabinet? For this set, yes.

How They Held Up Over Months of Daily Use

I have used this set since spring 2025, through every trip and through a full off season at home. The silicone bodies have stayed flexible. The lids have stayed on the same containers because I keep the sizes together. The four snap buckles still catch with a firm press. The seal ring has not torn. I have not had a container crack from being packed in the cabinet, and I have not had one warp from microwave heat. I reheat chili and soup in the 40.5 ounce container with the lid off, stir once halfway through, and let it sit a minute before I lift it.

The listing gives a temperature tolerance from -4°F to 428°F. I have used them in the freezer for soup and sauce, and in the microwave for leftovers. I do not put them in the oven, because the listing calls them microwave safe, freezer safe and dishwasher safe, not oven safe. That is a boundary I respect. The plastic lids are the wear point. After months of use, one lid is a little fussier than the others. It still snaps, but I have to line up the seal ring before I press the corners. If I rush, one corner sits proud and the buckle will not catch.

The most visible wear is a faint orange tint inside one 27 ounce container from tomato sauce. It does not affect the taste, and it does not come off with dish soap. I have stopped worrying about it. The silicone is BPA free, and the lid has a silicone seal ring, so I am not concerned about the stain itself. I just know that if I want a container for a light-colored sauce, I reach for a different one. That is the kind of small, ordinary compromise that comes with silicone.

I have also washed the lids separately and let them air dry on a folded towel. The snap buckles have not cracked. The silicone has not torn at the rim. The only real change is the stain and the fussy lid. For a set that lives in a moving vehicle, that is a fair record.

What They Do Well in the RV Fridge and at the Picnic Table

In the fridge, the rectangular containers are the ones I reach for first. They fit the shelf in the 6 cubic foot fridge without leaving a dead corner. The flat lids let me stack a 27 ounce container on a 40.5 ounce one. The 16.9 ounce size is good for a half onion or a lemon cut into wedges. The 11.8 ounce size is good for a little bit of leftover bacon grease, though I let that cool first. I label with a piece of masking tape and a pencil, because tape comes off clean and pencil does not bleed in the cold.

At the picnic table, the containers earn their keep. I fill one with chopped onions and peppers for the Blackstone 17 inch griddle. I fill another with grated cheese for smash burgers. When Ray runs the Gas One GS-3400P as a backup burner, I can carry salt, pepper and oil in small containers and set them on the table without bringing the whole spice shelf. The lids are secure enough for a short walk from the galley to the table. I would not turn a full container upside down and shake it, and I would not carry thin soup in a lunch bag without a second bag around it. That is not what I bought them for.

One unexpected use is a bread box. A half loaf of bread or a pack of tortillas goes into the largest container, and the lid keeps it from drying out as fast in the RV fridge or on the counter. I do not expect it to keep bread fresh for a week, but it does better than an open bag. On a rainy day, that is enough.

Where the Annaklin Set Falls Short

The first annoyance is the lid. Four snap buckles are secure when they are all engaged, but they require a firm press. If your hands are stiff in the morning, or if you are trying to close a container while holding a hot pan, this is not a one-handed job. I set the container on the counter, line up the lid, press the center, then press each corner. The seal ring has to sit flat. A rushed lid is the main way these fail in daily use.

The second annoyance is that silicone is not rigid. A full 40.5 ounce container of chili has some give when you pick it up. I support the bottom with my other hand. I do not stack heavy cans on top of a full container in the fridge. The containers work best when they are treated like what they are, which is flexible storage, not a structural box. The staining is the third thing. Tomato sauce, chili and turmeric can leave a tint. It is cosmetic, but if you want the set to look new, this is not that kind of product.

The set also takes up more room than you think when the pieces are full. Eight containers in the fridge at once is a lot of fridge. I usually have four or five in use and the rest collapsed. If you fill all eight, you will need a second shelf. That is not a flaw in the product, but it is a planning detail.

The collapsed set gives me back roughly half an overhead cabinet, and in a 25 foot rig that is worth more than another gadget that only works on a counter.

Who This Is For

If you cook in a small RV, a travel trailer or a camper van, and your fridge is a 6 cubic foot box with no room for wasted height, this set makes sense. It is also good for retirees who prep ingredients at home and carry them to the campsite, or for anyone who packs lunches for day trips and wants the containers to flatten out afterward. If you already have a narrow galley drawer and one overhead cabinet, the Annaklin containers are a practical way to use the overhead space without filling it permanently. It is also a good fit for a retiree who cooks at home in Salem and then carries prepped food to the rig. I do that with chopped vegetables and a batch of soup. The containers travel in a tote bag, and they do not add much weight.

Who Should Skip It

Skip this set if you need rigid, stackable containers for long-term pantry storage, or if you regularly carry soup and sauce in a lunch bag and expect a dry bag at the other end. Skip it if you dislike pressing four buckles or if you want containers that stay looking new after tomato sauce. Also skip it if you are cooking for a crowd and need large volumes in a single vessel. The 40.5 ounce container is the biggest in the set, and it is a lunch-sized amount for two people, not a batch of chili for six. If you want a container you can fill with soup, toss in a backpack, and forget about, buy a screw-top jar. The Annaklin set is for storage and short carries, not for rough transport.
