This is a Pearl Metal mini trivet. I used it when placing small pots on the stovetop. I only used it on an indoor stovetop and not outdoors. The entire trivet has been cleaned with kitchen detergent. It's made of cast iron and has some weight, so it's stable when placed on the stovetop. I think it's in a clean condition with almost no dirt or scratches, but the enamel coating is originally a bit rough. Outer diameter 14cm, made of cast iron, mini enamel finish, Fale HB-4198 [Product Description] You can use small pots and pans on a gas stove! This mini trivet prevents small pots from wobbling. You can place small pots and coffee pots that don't fit on a standard gas stove trivet. *This is an auxiliary tool for placing small pots and kettles with a diameter of 14cm or less.
