The abundance of “Satetsu” (sand containing iron), “gantetsu” (rock containing iron), sand, and clay used in the manufacturing of molds and charcoal led to the birth of cast ironware production in the Iwate and Yamagata prefectures of Japan. Nanbu “Tekki”, or ironware, has been produced in Iwate prefecture for more than 400 years, and is highly regarded by the Japanese for its beauty. Perfect for the desk of any turtle lover! This paperweight is made of cast iron and the dimensions are approx 2.75" X 2" X 1"
