Techni Ice HDR 4 Ply Reusable Ice Packs / Hot Packs (5 Sheets)

Great product, works well for transport. I use it for a low temp ice cream, -30 F, works great for a short time.

Great product to keep on hand during travel for use in a pinch - brought it for insulin, ended up using it as an ice pack for a pulled muscle. Handy!

I used ten of these sheets to pack frozen beef in a styrofoam container and shipped it overnight from Wisconsin to California. The contents, along with the frozen sheets, arrived frozen solid over twelve hours later! Wonderful product!
