I really liked the product, overall it does what it's supposed to do, BUT I think it was made a bit flimsy, right off the bat one of the containers came with a broken handle. It was only one which is why I didn't bother to return it, but just a heads up to anyone that orders this product. It's a bit frosty in the picture because I am currently using it to freeze veggies.I love how clean it makes frig look. A lot of food gets wasted when my kids can’t see what’s in containers. Only thing is make sure to not let dishwasher get too hot. 1st wash 2 of rectangle containers got a little warped so lid was hard to get on. I stored empty containers with lids on to get them back in shape which worked. Now I put on top rack of dishwasher which doesn’t get as hot. Square and Round container lids seem to go on much easier. I love the organization of the frig now. I also love storing in pantry. So much food goes to waste if you can’t see it. Makes everything uniform and in a weird way so you can make faster food decisions. I got easy peel labels on Amazon so I can also use in freezer. These will not melt in microwave but they get that white crud which ruins clarity. Don’t mind as I’m getting them for organization where I can easily see food. It cuts down on wasting food since I can see it vs rotting in back of frig. It also cuts down on time cooking since I can locate food items faster.The reason I didn't like these is that they sure don't close easily. You have to fight to make the sides go down. Need to work on this. I'd try another kind next timeVery nice seal wellFirst some reason I thought there were glass containers, but I was disappointed to find out they weren't ?I'm ok with them. They are hard to close. But they work. Not as large as I thought but they fit well inside each other for storage.I am very impressed with this set !I love this Tupperware. It is so easy to clean. I left spaghetti sauce in my fridge for a week and it didn’t stain my bowl! A little soap and water - no scrubbing or fancy tricks, it comes right off!I have noticed the lids will warp a little if you don’t unsnap all of the sides. But it hasn’t effected the seals any. And Don’t cut in the Tupperware. It will cut the plastic and then the plastic gets wonky.Other than that it’s a great set. I’m going to get another set. I’ve loaned a couple pieces out to family and I’ve become the Tupperware lady now. I want my stuff back!Pensé que estarían delgados pero no están gruesos y resistentes, además vienen de diferentes tamaños me gustaron mucho, son muy útilesPaid a lot of money. Saw the same stuff in the dollars store. Could have saved my self $50.00. Worse thing I ever bought on Amazon!
