Even gearheads will doff their jeans and T-shirts and get dressed up once in a while. When they do, they can add a pair of silver speedometer and gauge cuff-links supplied by Cuff-Daddy. These racing-inspired replicas feature an authentic-looking 5/8-inch-diameter speedometer that attaches to one cuff, while the other contains an equal-sized fuel gauge. Each one features an acrylic coating for lasting protection and is covered by Cuff-Daddy’s lifetime warranty. The $20 (including same-day shipping within the United States) price includes a hard-sided presentation box. Check them out at www.cuff-daddy.com.
