Kaatsu Training: I've created my own original arm belts. They are wider than the ones for beginners, so they constrict more firmly. Size: Arm circumference, approximately 27cm to 43cm Width: 3cm The color is the one in images 1 and 2 (green). *Please be careful not to over-tighten! *These are handmade original belts, so please understand before purchasing. *No price reduction is available. Immediate purchase is OK. *Free shipping (Yu-Packet Post Mini).
