Let's face it: Using a coaster is typically a pretty hard sell, even when there is one readily available. These carbon fiber coasters from Carbon Fiber Gear, however, look good enough that you'd want to use one even when it isn't necessary.

The carbon fiber coaster set comes with four coasters and a stainless steel display rack. There are little rubber feet on the underside of each coaster so that it doesn't scratch or scuff surfaces.
