CUSTOMIZED FIT FOR FAST RELIEF: Our Copper Thumb Brace is one size fits most (men and women!), and can be worn on either the left or the right hand. The adjustable straps mean you can tailor the fit and compression level for your perfect fit - no more guessing! It also features a metal splint for added stabilization, which you can bend to further customize the fit, or remove completely for more gentle compression. As a bonus, it keeps the wrist stable and secure as well.
