Thank you for viewing. ● This is a shoulder joint immobilization brace. I purchased and used this at the hospital due to a hairline fracture in my left shoulder joint. It immobilizes the left arm from the left shoulder with this brace. The fingertips are movable. It can be used and worn on either the left or right shoulder. I purchased it in June of this year for 7,420 yen. The shoulder-to-arm strap and the belt that runs across the back to secure the arm can be adjusted. It's designed to fit anyone. It's easy to put on and take off, and it fits well. ● I wore it for about a month, but I actually used it for about 20 days, so it's clean. It has been disinfected with alcohol. I will give it to someone who is planning treatment or who wants to use other braces.
