The Style For the intelligent problem solver with his game face on. Puzzle Cufflinks are simple and stylish and make for an interesting accent to a man’s appearance. Both sides of the cufflink have been made in the shape of a puzzle piece and are smoothly rounded out from every edge. Another set of puzzle cufflinks is offered with the puzzle pieces reversed. By design, these cufflinks have no moving parts like bullets that can sometimes break or get loose.
