Color coding makes matching tops to bottoms easy at a glance. They hold nice amounts. ### ⭐⭐ 2.0 out of 5 stars The woman selling them did a fantastic job at showing me how they worked etc *by K***Y on Reviewed in the United States on November 20, 2017* I bought these at the Puyallup Fair in WA state and paid about $100 for 5 sets. The woman selling them did a fantastic job at showing me how they worked etc. However after I started using them, I've discovered that the lids do NOT always close correctly. I can always clip 2 sides, but the opposite 2 sides are much harder to close. So hard, that I've broken one of the lids. This alone make them useless. I would not purchase these again. The other downfall is when you stack them in the fridge, the container below does not always keep it's shape. One last irritation is the little button on top that opens and closes to ventilate in the microwave. It easily pops off while washing or pulling open. I ALSO found a slight white residue after washing them in the top rack of the dishwasher, as stated by a previous reviewer. I'm giving it 2 stars because they are still functional, even if they are faulty. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Reduces Storage Space *by K***N on Reviewed in the United States on February 23, 2018* The rectangular containers can sometimes be difficult to get the lids to securely attach to the containers. The larger rectangular containers are the most difficult to get the lids to securely attach to the containers. The round containers are much easier to get the lids to securely attach to the containers. The round containers can be more difficult to sore away though. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/564141849-smart-storage-flat-stacks-bpa-free-silicone-collapsible-storage-containers](https://www.desertcart.pl/products/564141849-smart-storage-flat-stacks-bpa-free-silicone-collapsible-storage-containers) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-28*
