I purchased these at an esthetic salon about a year ago. The wrist & ankle supports are unused, and the arm supports have been used twice. There are a total of 6 pieces, all size M. These far-infrared fiber supporters are designed to lead you to your ideal body in a healthy way just by wearing them every day. They have a high heat retention effect and far-infrared effects, warming the body from the core and boosting metabolism. They promote blood circulation and care for lymph and uneven fat. They can be worn during sleep or daily. They can be used semi-permanently. (Quoted from the website) The box for the wrist & ankle supports has a dent, but the contents are not damaged. The retail price of these items is about 50,000 yen in total. - Size: M - Color: Black - Brand: AILE - Made in Japan Thank you for looking.
