TheraBand (Black) 2 meters. You can purchase it directly without any comments. We will ship it the same day! There are 8 types of TheraBand, and the strength varies depending on the color. (Weak: Yellow → Red → Green → Blue → Black → Silver → Gold: Strong) Black is suitable for strengthening the inner muscles. I myself often used it for injury rehabilitation. Please refer to the following as a guide for choosing the length: ・Full body training (when hooking on the feet) 2 meters ・Shoulder training (tying to a wall, etc.) 1-1.5 meters ・Wrist and finger training 1 meter Due to the nature of the product, it is easily torn when wet, so please use and store it in a place without moisture. There may be a white powder on the product, but it is to prevent the rubber from deteriorating, so there is no problem with its properties. The roll in the first photo has been cut. We can accommodate requests for length and bulk purchases, so please feel free to comment if you have any requests or questions. Also, if you have any questions after purchase, such as how to use it, physical abnormalities, or rubber deterioration, please feel free to comment. We will do our best to assist you. We do not offer discounts other than for bulk purchases. Thank you for your understanding. Purchased from: Lind Sports Co., Ltd. Tiger Medical Instruments Co., Ltd.
