16-oz. Square Clear Deli Containers with Lids , Tamper-Proof BPA-Free , Take Out Food Storage Containers Space Saver Airtight Meal Prep Container , 25Pack

16 oz. containers: outside dimensions are 4-3/8 x 4-3/8" sq. (top) and 3-3/8" x 3-3/8" sq. (bottom). For my purpose of finding disposable containers, plastic is fairly sturdy to the point of being reusable. Plastic is definitely not as thick as more expensive reusable storage containers though. Leak proof test yielded positive results. These containers do not leak! What a surprise, since the lid doesn't appear as if it clicks and seals to the rim of the container tightly and securely enough. Like others have mentioned, the purtruding lip along the edge of the container itself can be somewhat in the way, but lifting the lid is not difficult. The inside bottom is fairly flat with minimal interior indentation. Containers stack well whether with or without lids.

These are probably the best and most practical containers for food storage. I’ve tried many different brands and materials, including plastic and glass, brands like pyrex, joseph joseph, sistema klip-it, sistema to-go, collapse-it food storage containers, vremi silicone food storage, kinetic gogreen glassworks, rubbermaid easyfind lid system, just to name a few. These help keep my fridge and freezer organized, are easy to store, dishwasher and microwave safe. They’re nowhere near perfect: they’re not hermetic since an edge of each container clips off after the first use, a couple have stained a little when I’ve used tomato sauce in them, cheese has ruined a couple of them in the microwave, and a couple have gotten food incrusted/melted into the container when in the dishwasher. Still, remarkably, they’ve been the best in our household, help keep it all organized and make the best use of our tiny kitchen.

It's so much easier to settle on one type of plastic storage - I threw away a lot of my other mismatched plastics - and just use these for most everything! They don't take up much space when they are not in use, and the family can see what's inside when they are on the shelf or in the fridge. I've ordered these several times and highly recommend.

I love that they are clear, stack great in the frig, freezer and in the cupboard. There is a tab on one corner that you gently push down to remove the top. My husband has broke two of the tabs on the containers as he doesn't understand 'gently' even with instruction. Without the tabs they still work, seal just fine. I love that the 8 oz and 16 oz containers have the same size lid so it's easier to store and use without frustration of looking for tops to fit. I think it's a great product for the money. The outside measurements are 4 1/4" x 4 1/4" inside is 3 3/4" x 3 3/4". Inside height measurement is 3". Great for leftovers and lunches.

These are great containers. I needed something to start freezing lunches so I could bring them to work. These containers are the perfect size for that. The lids stay on and do not leak. They easily go from freezer to microwave with no issues. So far they are reusable. I have washed and reused twice now and still no leaks.

I have been using these food storage containers for more than a month now, and agree with the 100% 5-star rating given by the previous Amazon reviewers. They hold just the right amount of food for preparing ahead; they have see-through sides to minimize guessing; they are freezer/microwave/dishwasher-safe; and they are compact and extremely stackable both between uses (during storage) and while holding food on a shelf, in a fridge, and in a freezer.ProsVery compactStackableTransparentSeals tightlyDoesn’t open accidentally, yet opens easilySecurity feature (on first use)Freezer-safeMicrowave-safe (reportedly)BPA-free Polypropylene seems stain-freeInexpensiveConsTypos in Amazon listingTendency to water-spot in automatic dishwasherThinner walls and lids than we’re used to, but they are still thick enoughProtective rim/gripping surface could perhaps be slightly smaller to allow even more compact storage

try all these sizes they are space and time savers never waste time trying to find mis matched lids

These are a great size for either leftovers for myself or for the homemade food I make for my dog. They arrived promptly and in good condition. I also ordered a set in 32 oz and one in 8 oz but those are round. This is the best size and shape. I'm going to order another set. Perfect t for leftovers and for stacking in freezer.
