Review on Polar Tech Leakproof Viscous Refrigerant by Gabriel Rosenberg

I plan to use these products to ship products from my skincare line. When I first received them there was no barrier between the Ice Brix and the top of the box. They were simply thrown into a box and taped shut. As a result, I cut them into three parts and opened the box. Poor packaging in my opinion. Not sure if this is Polar Tech Industries, Inc or Revain Marketplace fault. Anyway, I lost three of them. But this is a great product. After freezing them, I tested them by leaving three of them in a box on my dinner table for two days, wrapped in brown wrapping paper, nestled around my homemade body butter. I wanted to see if they would stay cold during USPS 2 Day Priority Shipping and protect the whipped texture and quality of my body butter. Two days later I unwrapped the body butter and it was still cold and whipped. The Ice Brix were no longer frozen but they were still cold and they protected my product. Hooray! I don't know how they're going to behave in the back of a hot truck, but we'll see.
