12 gauge shotgun shell holder

I don't like having shell free in my vest's pockets so I designed these holders that snap together and attach to a backpack's strap. The shells I use hold well enough in place (i.e. won't fall freely) but they're easy to pull out if you need to. You should orient them so that the holder isn't pulled from the backpack's strap when you pull a shell out. You can affort to be a bit more gently when restocking.
