Bought these to put in our RV and the work great. Keeps items fresh and fit perfectly on our shelves.Love these. The seller is very responsible too, they sent me the worng color at first and I was a bit worried since the item is non refundable, but the immediately replayed and send me the right color. Totally worth it.The bottom of it hardThe Best!! Get rid of most of your stuff, and use these beautiful pieces to contain your necessities!These were smaller than I thought - but that was my fault! Otherwise they are great!I will like to say that this new way of storage food has been a mission to find good products and I can say I find this one very helpful. The containers it self are good and I used the dishwasher put it on delicate and dry them with a fabrics towels and they look amazing ..... the only think I wish for is if they had a extra spaghetti container since I go to costco and buy the pack of 6 and I also could make a diff with grain spaghetti but other than that great productIt takes a little maneuvering to get the tops to fit the seal perfectly but once it is sealed, it stays airtight. Overall, I am happy with this product.Just know before you buy that you can't return them because they're "flammable?"I haven't started using them because I changed my mind once I opened them up and saw the sizes. They're smaller than I was thinking. ?‍♀️
