Locklinks (Patreon)

Wondrous item, uncommon

This pair of brass cufflinks look like miniature locks. While wearing them, you can use a bonus action to use one of the following properties:

Secret Knock. You cast the knock spell from the cufflinks with the following changes: the spell has a range of touch, its knock is only audible out to a range of 30 feet, and it has no effect if the target is held shut with arcane lock. The cufflinks lose this property once it's been used for a second time.

Sleeve's Tools. You flick your wrist to cause a matching set of thieves' tools to appear in that hand. The tools disappear again if you are no longer holding them.

A bit of brass and a touch of class.
