[Trigger finger splint]: This finger brace is supported by an aluminum plate to prevent excessive finger flexion, which can effectively relieve trigger finger and stenosing tenosynovitis, reduce stiffness, and prevent finger joints from locking or jamming. Note that this just keeps the finger from over-bending, and please adjust it to a comfortable position when wearing it. [ONE SIZE FITS ALL FINGER]: The trigger finger splint can be worn on any finger, thumb, index, middle, ring or pinky, and the adjustable straps can be easily adjusted for a perfect fit. Velcro is durable and not easily damaged. [LIGHTWEIGHT and COMFORT]: Made of lightweight, breathable neoprene material. Soft and comfortable fabric provides all-day comfort. Small design keeps hands and fingers from feeling stuffy. You can wear it while working, sleeping, and exercising. [ALUMINUM SUPPORT]: Built-in lightweight aluminum brace provides superior support for stiff fingers. The aluminum brace prevents tendon entrapment and joint flexion to promote healing and reduce pain and discomfort.
