Rare Vintage Kim Craftsman Wood and Brass Target Earrings

A fun vintage pair of earrings marked "Kim", the trademark for Kim Craftsman, a well-known brand known for style and affordability. Starting in the 1950s, the created many unique and customized pieces. These most likely date to the 1960s-1970s. Resembling targets with their cocentric alternating circles, I haven't been able to find a pair just like these. Made of (possibly) Mahogany wood and Brass inlay, they measure about 1" in diameter (I need to take some photos). In good condition!
