[You need to finish your mission more than I need a keepsake.]
This official OneShot pendant necklace was designed by Audrey Waner. The clover pendant measures about 1.38 inches in diameter; it's a three-dimensional, translucent resin charm attached to an electroplated zinc-alloy outer ring. It hangs from a brass chain and comes packaged in a keepsake box.
(This new production run includes a number of design changes to improve the durability of the pendant, including a soldered bail, improved adhesive, and a clear coating to protect the outer ring.)
