This is a set of 10 HIRAKAWA Hiyayari Gel Scarves (Blue) HG-SFB-BL. The Hiyayari Gel Scarf doesn't require refrigeration or freezing. It can be easily reused simply by soaking it in water, retaining moisture for a long time and cooling the neck and head. Instructions: 1. Soak each scarf in water for 10-20 minutes. *Absorption time may vary depending on the situation. Rubbing by hand can shorten the time. 2. Once the gel has expanded, even it out by hand. 3. Wipe off excess water and simply wrap it around your neck or forehead! No price reduction, thank you.
