Put the brakes on somebody stealing your wine glass! AUTOArt's brake disc wine glass charm comes in four most popular colored brake calipers found on supercars and helps party goers identify their own glass of vino. The stainless steel rings clip easily to almost any size and shame of glass stemware and will remain shiny through years of use and cleaning. It's the perfect party accent for car enthusiasts and gearheads. The caliper and rotor is made of durable die-cast zinc, while the vented 12mm diameter rotor is fitted with a stainless steel plate that has been hand-etched and hand-polished to give the surface a hairline braking texture for realism. It rotates just like an actual brake disc.
