Ceramic DRGM Razor Sharpener in Box

Original ceramic razor sharpener stone in its original box. It is DRGM marked. The box shows wear and age but is still nice. I think it is unused. To use it, you would wet the stone, set the razor in it and with light downward finger pressure, move the blade around.It sharpener itself measures about 2 1/8'x 1 3/4'.
