A great product that keeps mines and fits comfortably in your hand. He came to me with a graphite mine, but I want to use it as a holder for the Cretacolor Black chalk mines, I have this very simple emersed. This also works really simple: Just press the button on one end and the "claw" at the other end opens. Now the mine may challenge or are pushed in or replaced. For me he has no mine rudimentary damaged or otherwise not working. Only the price I think was very high, but the quality is perfect and I think he's going to last.
