Established in 1892, the John Ritzenthaler company (Ritz) has long been synonymous with the finest quality in home textiles. Calphalon is a name equated with quality in the kitchen. This set of 2 black Calphalon potholders is made with 100% heavy weight cotton twill. This stain resistant fabric is covered with silicone for great grip control and is heat resistant up to 500°. The pot holder shape provides the right amount of protection without extra bulk and can be used with a right or left hand. Silicone treated fabric allows for great grip control when handling heavy pots and pans and is highly flexible, breathable and tear resistant. Each black pot holder measures 10 inches long and 6 inches wide. Machine wash cold, tumble dry low and remove immediately from the dryer.
