Looks like the kind of spring loaded pin they use on retainers, the ones that snap back on your finger and give you blood blisters haha, if thats the kind i would not be worried about losing one at all. Nice idea. Good work.Clip is spring loaded. My son and i have been riding with it this season and haven't lost one yet.
I plasti dipped the clip to have some protection when in the closed position.
if your interested PM me.
