I purchased this because the description says that they can go in the freezer and microwave, unfortunately microwaving these containers has resulted in damage and I had to dispose of some of them. The plastic started flaking in the bottom section if it gets too hot, so if you microwave them be sure to use a lower setting. The lids also cannot be microwaved. Do not drop these because they are very fragile, especially if you're taking them out of the freezer. I have probably a little more than half left that are undamaged at this point.
Not very durable
