It can be used for a wide range of purposes, such as muscle training, rehabilitation, and improving musical instrument playing ability. ① Adjustable Hand Grip (Black) Adjustable resistance: Easily change the resistance from 5kg to 60kg with a single dial. You can adjust it to your level, from beginner to advanced. Ergonomic design: Non-slip grip shape fits your hand securely. ② Finger Training Stretcher (Gray/Yellow) 3-level resistance settings: By changing the fixing position of the strap, you can adjust the resistance to 1KG / 2KG / 3KG. Wrist strap included: By repeatedly performing the action of fixing it to your wrist and spreading your fingers, you can efficiently stimulate the outside of your forearm, which is difficult to train normally. ◎Due to amateur photography, the color may differ from the actual product depending on your monitor settings and room lighting. ◎It has been opened once for photography and inspection, but it is a new and unused product. *Please take a look at my other items if you like＊* We offer a small discount for bulk purchases (人´∀｀)☆ #May_you_have_a_good_connection_with_Nijimusubi...
