AMSCO Disposables Meal Prep Containers- Premium Quality - 25 Pack of 12OZ - Mini Food Storage Bento Box - Reusable BPA Free Microwave and Freezer Safe Portion Control Trays

When I make a pot of soup I like to freeze it in individuals servings. These are just the right size. They hold up well in the microwave and clean fairly well. Unfortunately, a couple fell out of the freezer and the container broke. Oops!

So far these are exactly what I was looking for. The quality is better than expected. I will definitely be buying these again. so far there has not been any damage to the black bottoms when they have been used to heat food in the microwave.

Been using these for a month to batch freeze them for meal prep. One container came cracked but the seller kindly refunded for the broken one.It is very convenient for stacking and easy to clean. The portions are just right for what is described in the listing. It's not entirely leak proof, but thankfully haven't had any major spill.I found that the material is pretty thin, and after a month of use, I noticed more and more containers are cracking - the lid specifically. I am very careful with handling my containers, and I suspect it has trouble withstanding the freezer.For a long-term purpose, I personally would shop around for another product. For short-term, it is acceptable.
