Himark Chokin porcelain covered box

This covered box is 3.75" in diameter and 1.75" high. GW find for $1.75. I like glass, ceramic and wooden boxes and frequently buy them when they tickle my fancy. I mean that in the most manly sense. Ahem. Anyway, this Himark designed box was apparently made in the 1970s or 1980s and is kind of neat because of the explanation of the construction on the bottom. It is a nice quality piece and there are only a couple of examples of Chokin pieces on CW.
