Mermaid Purse

Carry small essentials on a key ring

A pocket case for earplugs, a SIM tool and spare coins shaped like a skate egg case, the mermaid’s purse found on beaches. Its four curling horns anchor the egg to seaweed; here one horn eye takes a key ring or lanyard, and the snug lid follows the same outline.
