Thank you for viewing! ^_^ I have used it several times, but there are no noticeable scratches or damage. Product Code: PUN10-MB Color: Marine Blue Dimensions: W290 x D210 x H14 (mm) Weight: Approximately 0.3kg Materials: Outer Material: Nylon, Chloroprene Rubber Inner Material: EXGEL® (Synthetic Rubber), Urethane Foam Lining: Urethane Synthetic Leather Three characteristics of "EXGEL" solve the three problems of "sitting": ① Elasticity that absorbs impact ② Flexibility that disperses pressure ③ Fluidity that reduces stress Even when sitting, people unconsciously change their posture from side to side and front to back. EXGEL conforms to these movements, fluidly dispersing not only vertical pressure but also the force of lateral shifts. The free movement of the gel reduces the burden on the body. Made in Japan products born from the hands of skilled craftsmen Products manufactured in a domestic production factory certified by ISO9001 are finished with high quality, one by one, by the hands of skilled craftsmen. "EXGEL Cushion" is born today, one by one, through the hands of many craftsmen.
