X100 Titanium phiten Leash Model Length: Approximately 50cm I haven't used it very often. I wore it when going out or playing golf. Please understand that this is a used item in relatively good condition. There are no noticeable scratches on the metal parts. There is no fraying on the black neck strap or the red ring parts. The metal fittings detach without any problems. I haven't worn it in the bath. I haven't worn it when sleeping at night. I don't smoke. Thank you for looking.
