Foam roller. Suitable for loosening the back and a wide range of muscles. Can be used on a wide range of areas such as the soles of the feet, calves, thighs, lower back, and upper arms. ・Size: 14cm in diameter 　　　　　33cm in length I love using it because it feels so good, but I have two of the same item and have one extra, so I'm selling it. Due to the high shipping cost, I would appreciate it if you could refrain from negotiating the price.
