This is a cover that completely waterproofs a child's arm cast, allowing for worry-free showering. - Product Name: Cast Waterproof Cover - Target: Child's arm - Function: Completely waterproof - Application: Easy to apply - Reusability: Reusable Thank you for looking. I used this about 3 times when my 130cm tall child broke their wrist. Water didn't get inside, and they were able to take a bath with ease! There are no noticeable stains, but please refrain from purchasing if you are overly concerned about condition.
