Name Rock

The story behind this? Ah, well I'll make it quick then-
When my family has dinner we each take turns setting the table, though we (referring to my other siblings) often seat members in different places each night, so we each have a rock or stone with our name on it which we put where we want said person to sit. Anyho, since my rock was the only white one, it got pretty dirty after a couple of years, and so my mum told me to get another, but I didn't want to just put my name on it, so I decided to paint on one of my spirit animals- the yin-and-yang magpie It won't be long now until the rest of my family start taking up brushes to their name-rocks too!
Also yes, the symbols on the left are my name for those who know japanese, or just look it up on google lol

Size? Idk, didn't really measure but I'd say around 10cm in diameter, fits nicely in your hand
