Polar Tech RE-FREEZ-R-BRIX RB30 Foam Refrigerant Packs, 31oz Capacity (Case of 6)

I do not remember at all where I got them from. I've had these for probably 6 or 7 years I don't know if I can post Amazon links? I looked at the rules and it doesn't say no so hopefully. I tried Google lens and even scanned the barcode on the back and nothing came up. This is the closest thing I could find https://a.co/d/0epRsOuh
