Our Thumb Splint with Wrist Support uses lightweight aluminum in the neutral position, which is bendable to fit the thumb and wrist perfectly for maximum support and immobilization on your thumb without affecting other finger activity. This splint is designed to support your thumb joints and ligaments and immobilize your thumb in place. Easy to remove and reusable.
It fits someone who has big hands from 5 ~ 10" in wrist circumference. Aluminum length 7.1" (from wrist to thumb). You can wear it right or left.
