The Gastro Flex diamond mold is a non stick and flexible pan made of food quality silicone that permits freezer to oven use between -58F and 485F. The Gastroflex is best used placed on a grill or perforated baking sheet to encourage even heat distribution. It never needs to be greased because the non stick and flexible qualities of the Gastroflex ensure rapid fuss-free turning out of pastries. Each diamond mold is 3 inches by 1.5 inch by .5 inch deep. Dishwasher safe and made in France. (P8011)
