"Ossium", latin for "bones" have been used as Memento Mori since the ancient Rome and Greece, when people would carry tokens and depictions of skulls and bones as a reminder of their mortality and that life is precious. "Memento Mori" literally means "remember you must die" which, to be honest, is so straight-to-the-point that I really respect it.
These little bones are only 1.5cm long and are cast in either solid recycled silver to remind you that life is precious. We're here for a good time, not a long time and all that!
