Bests & Worsts Reviews from Amazon

I bought these for a very specific purpose. I use them to make freezer meals that will fit inside my instant pot. I place a gallon freezer bag inside and use this to contain it to the proper shape. No more flat bags. Does this take up more freezer room, maybe some but being able to put the whole thing in the instant pot on crock pot mode without defrosting is such a time saver that freezer room is negligible. Talk about a time saver. If a time comes that I need more, I will purchase again.
