And yes, of course I made an herb grinder for the kitchen. We have a dark kitchen and this is sitting on the counter. I will be able to find it and it will leave off a nice glow. Food safe.
2 1/2 inches in diameter and 1 inch tall. Just put the herb in, tiny amounts, just enough for one dish, turn both sides in different directions and the herb comes out just ground enough, not like an electric grinder will do, but softer. The dryer the herb, the better it falls out. To clean, use a toothbrush under running water.
