Mini Curiosity rover papercraft in a plastic & metal capsule pendant, with copper shell stones. Made freehand (no template) with glue, scissors, x-acto blade, and paper.
Pendant is approx. 2” in diameter (so it’s somewhat large, as pendants go - quarter is shown for scale).
Chicon/Worldcon exclusive item: will be made available in the art show there, then listed at my Etsy if it does not get purchased at the convention.
