Review on Keep Your Homemade Ice Cream Fresh: SveBake Ice Cream Storage Containers With Lids - 2 Pack by Steve Atchley

I gave these 4 stars because there is no washing instructions on the container or packaging. Now, that right there, should have been enough for me to think twice. Of course not. I washed them using the top shelf of the dishwasher. They warped a little. They are still usable but they are now harder to nest together.Hand wash onlyMy mom always told me, if it doesn't say so don't assume so.
