Uses microparticle beads that conform to the body. You can relax by placing it on your neck, lower back, etc., and using it as you like. Compact, hourglass shape. Approximately 13.5 x 59 cm I'm selling it because I don't use it (^-^) Due to shipping costs, I would appreciate it if you could purchase it at this price. Please check the actual product from the 7th photo. ■Product Condition I think the condition is good, but please understand that it is a home-stored item. Please refrain from purchasing if you are concerned.
