Clarinet Lightweight Compact Double Case Strap - Buffet Crampon

This was included when I purchased a lightweight double case for my clarinet. This is a sale for the strap only.
As shown in the 4th image, it can be attached to the case and used as a backpack or shoulder strap.
It has been stored unopened and unused.
I am selling it because I usually carry my clarinet in a tote bag and do not use it.
Although it is unopened, it has been stored at home, so please refrain from purchasing if you are sensitive about this.
