Narumi's super heat-resistant glass cookware, a Cookmaster double-handled pot. This item is from the 1970s and is now a rare, discontinued product. It's perfect for cooking, and also a very cute item to decorate your kitchen. There is a sense of use due to aging, but I think the condition is not bad. Please check the photos and purchase with an understanding of used items. It can be used on direct heat, in the microwave, and in the oven. Also, it boils quickly and cools slowly, making it economical. It's said to be four times stronger than glass and super heat-resistant.
