I have created my original arm belt for Kaatsu training. It's wider than the beginner version, so it tightens more securely. Size: Arm circumference approximately 27cm to 43cm Width: 3cm The color is the one in the first and second images (orange). *Please be careful not to overtighten! *This is a handmade original belt, so please understand before purchasing. *No price reduction is available. Immediate purchase is OK. *Free shipping (Yu-Packet Post Mini).
