Trivets are 6 ó square ceramic tile with cork backing to prevent slipping and scratching. Trivets are sold individually and come packaged in a sealed clear sleeve with an artist's bio. Images are permanently sublimated onto the tile, leaving a glossy finish. Trivets can handle both hot and cold temperatures. While they are food safe, please do not submerge in water, put in the microwave, or in the dishwasher.
