These handmade Darth Vader cufflinks are just $22.49(USD) from Cuff Reations (I’m not sure what a “reation” is either). They have a great selection of cuffs, but none more sinister and powerful than this set. Although the Stormtrooper cufflinks are pretty cool too.
A little Sith in your wardrobe never hurt anybody. Well, except for the other guy. You know, the guy who gets force choked at the end of your wrist.
