Aosrky Supervised by a physical therapist × Dual Pressure Wrist and Thumb Supporter For Right Hand S Size Black Please refer to the images for sizing. The snug fit feels great, and it's also thin and easy to move in. Spring-loaded support and strips restrict overextension and hyperextension of the thumb joint, while the wrist wrap applies pressure to stabilize the joint and reduce stress on the wrist joint. Made with skin-friendly materials to maintain support and comfort even after long periods of wear. I intended to use it, so it's been opened, but it's a new, unused item. I only checked the contents. The opening of the bag was cut when I opened it (Image 15). The instruction manual is included (Images 12, 13, 16). Are you suffering from thumb pain? I will send it in simple packaging as shown in Image 16.
