The insulation bags are flexible, reflective, with thermal insulation outside and inside, they seem to work pretty well keeping cold chocolate chips from getting soft.

Will keep food at original temperature

They were great! Just what I needed.

I used to ship college care packages of frozen foods. Flattened 1/2 gallon frozen bags slid inside these easily. Stays semi-frozen for 2 days of shipping.

super nice size and self sealing

Ease to use value for money

I thought the bags were large enough to fit a round 8 or 9 inch two layer cake. Unfortunately it’s not. The bags nice but again, unfortunately, way to small for what I need them for. These seem to be the largest ones I see on Amazon. I’ll try to find larger ones in a store near me.

These were great for gifting frozen bags of home made fruit preserves. They were able to keep the jars frozen for several hours until the recipient was able to get them home and into the freezer. They look and feel like they are more expensive than they are.
