This is a stainless steel wire mesh purchased from Tsuji-Wakanaami in Kyoto. It can be used on a stovetop and has various applications. I mainly used it as a substitute for a toaster for bread. The size of the wire mesh is approximately 22 cm (square), and the thickness is about 3 cm. I am selling it because I haven't used it for several years. It shows signs of use. I believe it can be used normally without any problems, but please understand that it is sold as-is and non-returnable.
