Finger supporter set of 4. Finger protection, fixation, trigger finger, jammed finger, tenosynovitis. Free size. Finger supporter. Tennis finger. Short. 4 pieces. I bought these because they were described as short, but my fingers are extremely short, so they were a little too long, and I gave up on using them. I tried one on after opening the package.
