A simple bow with arrows, the bow is copper and the rest is brass. Medieval weapons make for simple but effective earrings, and work well for your next TTRPG game :D
I have also made dangling flail earrings that were fun, but maybe less obviously recognisable than these.
This is beautiful and timely. The bow and arrow are symbols of the goddess Artemis.
It would be so cool for one of the astronauts to have a set of these.
