The king of Atlantis' cufflinks.
Locking part has the JL logo.
You can find other models in the "jewelry" section of my shop
Send me a private message if you want a custom monogram (i.e. your initials) instead of "JL" (custom will be approximately +$10 versus the regular "JL" version).
[Edit01] Picture is version 01. Active version has a larger locking part to fit more shirt models (see digital previews).
