FOR THIS SPLINT

✓ if you have enlarged joints, please be sure the sizes you choose will fit over the joint
✓ when sizing, you want a snug fit but not too tight
✓ try bending the finger slightly while measuring to find variations in sizing until you find a good average measurement.
✓ most of the splints are adjustable within a ring size or so, contact us for help
