Thank you for viewing. This is an arm holder designed to securely immobilize and protect your arm in cases of fractures, sprains, dislocations, and similar injuries. I purchased it in 2024 after thumb surgery, but I only used it a few times, so it's in very clean condition. It's easy to adjust the size, allowing you to put it on and take it off yourself. The breathable mesh material and the shoulder pad (light blue part) reduce the burden on your shoulder, making it comfortable to wear for extended periods. There is a pocket on the back, which is very convenient for holding your phone or small items. - Color: Black - Material: Mesh, Neoprene - Design: Sling type (with thumb loop) - Size M: Length 41cm x 16cm, Shoulder strap adjustable from 42-81cm - Condition: Purchased in 2024, used only a few times, in excellent condition I aim to ship quickly. I hope this will be helpful to those who need it. ★ Stored in a smoke-free environment ★ No pets
