Thank you for viewing. Sat-chan Doctor Strap Satoko-chan Nurse Strap set. It's a ball chain type, so you can remove it from the strap and use it. I got these over a decade ago. The backing card and bag may have deteriorated somewhat. These have been stored at home for a long time. Please understand the above before purchasing. #Yellow #Sat-chan #Satoko-chan #Doctor #Nurse #Strap
