Owned by family. This is a digital hand grip meter. It can register 19 users. I think it can be used for club activities, etc. I used it a little and then stored it. Batteries are included. I have also confirmed that it works. The settings have not been initialized, so please reset them yourself after purchase. Thank you to anyone who will use it. It comes in a box, but if you only need the contents and the instruction manual, I will discount the shipping cost and ship it anonymously via Yu-Packet Plus. Please feel free to comment.
