Tidehalf

Share a split keyring that locks into a disc

Two halves of one tide. A 46 mm disc is split by a wave, and both halves are the same shape turned round, so you print two, engrave a name on each and give one away. Clip them to two keyrings; when you meet, the waves lock back into a full circle.
