Dia-Pak Refrigerant Gel Packs Freeze Solid Cooling Gel | GEL8OZ-PP

Perfect cooler pack for a small cooler, lays flat on bottom, top r sides.

These Medicool gel packs fit in my Medicool Pen Plus case perfectly. During a recent trip the frozen gel pack kept my refrigerated medication cold for more than 10 hours. I'm very pleased with this purchase - works exactly as promised.

I have used a Medicool to store insulin pen needles and supplies when traveling for 10 years. After a number of years the Gel Packs develop slow leaks and need to be replaced. The leaks are so slow that the only way I detect a leak is by careful inspection after the Gel Pack does not seem to be as plump as it originally was. I usually try to keep two good ones in the freezer ready to go. They have worked well for me over the years..

Keeps everything cold. But ice bag is thin and will break easy

Like this product, it is a replacement for an old gel pack for my pen plus diabetic case
