I used this when my child broke their arm. ⭐︎ Arm Sling Pink mesh arm sling It has the child's favorite character and ribbons attached. It's pink mesh with a shoulder (neck) pad, so I think it reduces neck pain. Available in 2 sizes. ⭐︎ The cast cover is a bonus. For the arm. There's a tear on the inside, but not on the outside, so I don't think water will get in.
