Picks over cancer sticks! True, this ashtray could be used for smoking, but it’s also quite effective at holding different bits and springs. Its black metallic finish exudes sophistication and adds a touch of luxury to any workbench. With a diameter of 4 inches, this ashtray also doubles as the container for three mini double sided pinning mats that with it give you multiple surfaces to organize all those small parts that seem to dominate the lock picking hobby.
