The Master Sword and Scabbard that we have has no way to attach a strap. These clips remedy that. They can take a 1 inch web strap. Recommend you use epoxy to glue them on, and don't forget to sand and scuff up the smooth plastic surfaces beforehand so the glue has something to stick to. 

Obviously, these could also be used in other places for web straps, but this was my specific use case, and hoping this helps anyone else who has the same need!

Enjoy!
