Kinuya Gokudan Silk Arm Warmers have the effect of raising body temperature by +4.4℃!! 90% Silk 9% Polyester 1% Polyurethane I received these as a gift but am selling them because I don't use them. The box is partially crushed. Although it is a new, unused item, please understand that it has been stored at home by a private individual. Because of the thickness, I will ship it directly in a bag via anonymous delivery. Instant purchase is OK ⭕️ - Color: Gray - Temperature increase: +4.4℃ - Product name: Gokudan Silk Arm Warmers - Product number: S05118-06 Thank you for viewing.
