Components and how they matter
- Moldable thermal plastic — adapts to your thumb shape to provide stable support while allowing natural motion in the hand.

- Indications — designed for thumb strains and sprains, tendonitis of the thumb, arthritis of the thumb, skier’s thumb, and for larger thumbs on average male users.
Usage tips and who this is for
- Apply with proper tension to ensure circulation is not restricted by the straps.
- Place the thumb into the brace and then wrap the straps around the wrist and thumb for a secure fit.
- Suitable for individuals experiencing thumb strains, sprains, tendonitis, or arthritis who need added support without limiting finger use.
- Test fit on a small, non-sensitive area first if you have sensitive skin or a history of skin irritation with braces.
Keep the device clean and dry, and store away from direct heat when not in use to maintain the integrity of the moldable material.
