Safe Material: These knuckle joint support braces are made of elastic neoprene material, which is latex-free and helps warm your hands while soothing sore, stiff finger joints to increase strength and function. The side-insert straps are hand washable. Nice Personalized Fit: The wrap-around support strap is adjustable to help relieve pain from conditions such as tendonitis and sprains. This splint is not only ideal for personal use but also a thoughtful gift for friends, family, and loved ones. Unrestricted Support: While keeping the MCP joint aligned during recovery, this finger stretcher wraps only the upper part of the palm and a small portion of the fingers, leaving the rest of the hand free for movement. It is lightweight and comfortable for extended wear. Adjustable Finger Straps: Includes 2 black right-hand ulnar deviation straps (size S), suitable for hand circumferences from 6.75" to 8.25" (17.1 to 21 cm). Ideal for replacement and daily use. Please refer to the image for specific sizing details. Effective Pain Relief: These hand splints provide a reliable rehabilitation and therapy solution for pain management, joint degeneration, skeletal deformity, and ulnar drift treatment. Designed to immobilize joints and fingers for long-term use, the flexible closure allows for easy application and adjustable fit to meet individual needs.
