Sistema18-Piece Food Storage Containers with Lids for Lunch, Meal Prep, and Leftovers, Dishwasher Safe, Clear/Blue

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.

My husband is a paramedic and takes 2-3 meals per shift. We’ve been using some other 2 cup containers for several years, but when I went to get more, they’ve changed something and he hates them. I went to the store and bought several different containers to try to see what he liked, and these were the winner! They’re a good heavy duty plastic. The lids lock on, so he hasn’t had any leak (yet). I’ve also put spaghetti up in the fridge in one and it didn’t stain. This size holds a 6oz pork chops, a half cup of rice and a cup of broccoli without squishing anything down. The first set got washed at least three times weekly and hasn’t had any trouble going through the dishwasher or being reheated in the microwave or warping. A little pricier than ziploc or Rubbermaid, but the quality is definitely worth the extra $2-3 you spend.

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.

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.

This container/storage system has a variety of sizes and are stackable for more similar sizes. I've owned my first set for several years now with no problems. The only issue I have with them is the lids are difficult to clean between the seal (by hand cleaning) and when in the dishwasher the lids or lips of the lids tend to hold water, so they need to be air dried afterwards.

These were cost friendly alternatives to my rubbermaid brilliance. They work great. The microwave use and dishwasher cycles seem to eventually catch up to any plastic, but these have held up well, maybe ever better then the more expensive Rubbermaid brilliance. I like them

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

These 33 oz. containers are the perfect size for storing leftovers in the refrigerator. They are transparent so you can easily see what is in them without having to open them. The KLIP-IT design locks and unlocks the lid, making it easy to open and securely close the lid with minimal effort. I highly recommend this product.
