Testicle Keychain by I Heart Guts

Let it all hang out with the cutest testicle keychain ever. These family jewels produce sex hormones and sperm. Testosterone makes the man, helping sperm find and fertilize those eggs. Sperm is the swimming cell responsible for the studly art of reproduction. Absolutely nuts! The engraved back of the keychain and cardboard display both say: "Testicle: Having a Ball." Zinc alloy with soft enamel, polybagged. The testicle part of the keychain measures 1.93" x 1.9". Designed in the US, made in China.
