Crazy Kool Unique Vintage Shell/Key/Glass Pendant

Crazy Kool Unique Vintage Shell/Key/Glass Pendant. Hand blown (?) glass around a vintage key with a shell attached. The shell has a silver ball inlayed in petal (not sure what to call it haha). Attached a leather string to show how I would attach a necklace. The glass part is signed in the back as well. Very neat piece! Going to call this one of a kind. :)
