Thank you for looking. This is a set of Sato-chan Doctor straps and Satoko-chan Nurse straps. They are ball chain types, so they can be used even after removing them from the strap. These are from over ten years ago. The bags and backing may also be deteriorated accordingly. These are items that have been stored at home for a long time. We appreciate your understanding of the above. #Yellow #Sato-chan #Satoko-chan #Doctor #Nurse #Strap
