In our archery club there are regular events for guests to try out shooting with a bow. Especially kids do handle the guest bows quite roughly sometimes and the sight pins are most of the time the first thing to hit the ground and break. This is a replacement pin head that can be fitted to the left metal thread after removing the previous pin head. The diameter of the opening is a little smaller than the average pin diameter, it's designed to be glued on by heating up the metal pin and then melting it on directly.
