This is a set of 10 HIRAKAWA Hiyayari Gel Scarves (Bulk Dry) in Green, model HG-SFB-GR. The Hiyayari Gel Scarf doesn't need to be refrigerated or frozen. It can be easily reused simply by soaking it in water, and it retains moisture for a long time, cooling your neck and head. How to use: 1. Soak each scarf in water for 10-20 minutes. *Absorption time may vary depending on the situation. Rubbing it by hand can shorten the time. 2. Once the gel has expanded, even it out by hand. 3. Just wipe off the excess water and wrap it around your neck or forehead! No price reduction, thank you for your understanding.
