Concerned that your significant other is doing the sidepiece shuffle with some cheap coquette (or coqsieur) behind your back? Then The's Anti-Cheating Ring may be just the chastity-ensuring device for you.

A seemingly ho-hum wedding band on the outside, the Anti-Cheating Ring contains within it a clandestine engraving of the words "I'm Married," that, when pressed against the wearer's skin, leave an imprint that cannot be as easily removed as the ostensibly sacred ornament that made it.

You can't put a price on fidelity — but The Cheeky can: $550.
