The Cressi Bridle Beads are used to make up a bridle to insert in to the spear rubber. Without bridle beads it would be very difficult to load a gun as the beads are what stop the bridle from coming out of the rubber when loaded. They are pushed in to the gun rubber using some silicone spray and a T-tool and then tied off with constrictor cord.
Beads can be reused.
