This is a Nakao Aluminum Seisakusho stockpot, purchased for the list price of 7,000 yen. I am selling it because I switched to an IH stove and no longer need it. It has been cleaned with boiling water and citric acid. While it shows signs of use, it is a durable, professional-grade product and should still be usable for a long time. Please understand that this is a used item. Product Description: The rim is folded and pressed, which minimizes distortion and deformation. The thickness is uniform throughout, and the heat distribution is even, preventing uneven cooking. This product is suitable for heavy-duty professional use. ● φ240 x 110 t=2.0 ● Material: Aluminum
