This is called an "Okonomi Cup," a commercial kitchen tool used by okonomiyaki restaurants to portion out batter and ingredients when preparing a single okonomiyaki. Some restaurants allow customers to make their own okonomiyaki, so some of you may have handled these before. The small size has a diameter of approximately 11cm and a capacity of about 350ml when filled to the brim. The shape is essentially a stainless steel cup, so it can be used for purposes other than okonomiyaki. Stainless steel is excellent for corrosion and heat resistance, so it can be repurposed for uses other than food and beverage. Personally, I use it for melting wax. I am selling one, but I have about 40 unused of the same product. I will not accept significant price negotiations, but I welcome the purchase of multiple items. Regarding shipping, 20 pieces can be shipped in an 80-size package. This product is stored in a storage shed within the same city, so please allow a few extra days for shipping. Thank you for your understanding. Keywords: measuring cup, tray, kitchen equipment, bowl, colander
