Rooster Trivet. Trivets are screen printed, kiln formed glass, 6" square, with rubber bumpons on the bottom to protect your surfaces. Trivets will handle very warm dishes, they also make great accent/art pieces - use a plate holder or picture ledge and attach it to your wall or prop it up in a window when you're not using it. While it is dishwasher safe (we like the china/light cycle), we recommend hand washing.
