Sistema KLIP IT Rectangular Collection Food Storage Container, 33.8 oz./1 L, Clear/Blue, 2 Count

I discovered these by accident because a friend at work was using them to bring lunch.They're great, and I've thrown away most of my Tupperware and Rubbermaid containers and replaced them with these. Also now less in the habit of using mason jars or putting leftovers in a bowl covered with plastic wrap.The critical innovation here is that there is a seal made of a softer plastic. That allows the rest of the lid to be made of harder plastic, and allows for the addition of latches without deforming it. This leads to several practical benefits:1) Because of the latches, the containers will not spill if inverted or handled roughly. Though they are not leakproof, at least the lids will stay on, unlike most competing square containers.2) The tops are relatively flat and so containers of different sizes can be conveniently stacked, and can generally be moved around the kitchen and carried in a stack without six hands or two extra trips. The sizes are well chosen to make this practical. The amount of fridge space this recovers is considerable.Some things to keep in mind.1) Like any plastic container they will stain when used to hold certain foods, particularly tomato-based chilis and soups.2) They will sometimes leak if filled with liquid and inverted.

Nice set and good quality

This is my third purchase from this brand of sealable containers.... they are durable , quite leakproof if gasket is securely in place, and I appreciate the stackability and ease of organizing. They are top rack dishwasher safe (I leave them to air dry after) and use them all the time! After many uses, you may experience discoloration from red sauces and “burn” marks from food that gets very hot when microwaving but honestly, if you are looking for a safe and lightweight alternative to glass and - like me- need to be able to organize your containers, Sistema does NOT disappoint ! You way want to start with two sets in order to get a nice assortment as 20 is a minimum for a family in my opinion.

What to get the relative who wants nothing at Christmas? Sistema! She started a new job and was looking to make food for several days, but only had recycled smaller containers. She is so happy with the new containers. The shapes fill the frig and don't leave a lot of dead space, seal really well and don't leak. Dishwasher safe with no residue. Now she is looking to get more. FWIW, I picked Sistema b/c it's what I use at home. The wide variety of sizes makes them ideal for leftovers and prep as well.

I love Sistema product, I bought the bake it collection before. The quality is awesome. I like how it have a strong suction when you close it. However, this product seem don't have the strong suction as the bake it collection but still decent. And the price is so much better!!!!!Because of the strong plastic material and the product design, you can't really stack it all together. But it wont take up too much space because the container actually isn't too big.Personally I only use the container for fruit and baking product. But I tested for this product for leak proof, only the two tiny circle containers can hold the water. The other just leak right away. So if you looking for something to keep your soup, probably you should look for another brand.

We have bought multiple times and variations. Reallyike how easy to clean and how seals can be removed and cleaned we have just about every combination of sizes. We typically use only for refrigerator. I don't think they hold up as well if you microwave with them often.

Best of many tried. Over years of trying other brands, these are my favorite. Easy on/off lids with tight seal.

I have used these 1 L Sistema containers for small parts storage, for neatly packing toilet, electronics, and first-aid items when travelling, etc. Much more convenient than a "1 liter (or quart) ziploc baggie", and since they are clearly marked 1 L and easy to examine, US TSA and other national airport security inspectors have never given me grief about it.One thing that doesn't bother me but that could bother you, because it differs from the item's description, is that this time the plastic trim and tabs are green, not the blue that I'm used to.
