Review on 👐 IMAK Arthritis Thumb Stabilizer, Size: Medium (Up to 3-3/4") – Flexible Support for Thumb – Enhance All-Day Comfort – Alleviates Thumb Pain – Reversible for Both Hands – Breathable Design by Jesse Jewett

Sizing Info: My palm measures 3 and 1/4 inches above my knuckles, the sizing is perfect, snug but not too tight. I read the reviews and everyone said they were big so I was afraid to buy the small ones but they were too tight and I swapped them out for the medium ones. Pros: Nice soft material, flexible so you can move your thumb if you want. Cons: There's a large pad in the palm area that can hinder use of a computer mouse a bit, not to fully isolate the thumb but more as a support brace.
