At first, i kept them as a memento and for the possibility of re-using them (if possible, re-filling them) i used them as a "adaptor" for undersized caps, that i found at the stores meant for capguns. These caps are usually 3-4mm in diameter and they fit inside of the empty 7mm cap bodies nicely+they take up the room in the cartridge and they acted as a gas-seal. These caps are far weaker than the real Japanese caps but, they where all that i could find 4-5 years ago and they did operate the Marushin MP40/M712 that i tried them in..
