This is only the wire mesh for a tempura pot. As you can see from the back, the four corners that hook onto the pot are about 1.3 cm, so I think it can be used for pots with a diameter of 21.5 cm to 23 cm. It's not bare metal, but has a matte silver coating like Teflon. There's a hole to hook chopsticks for removal. I don't know the manufacturer. Size: Diameter 21 cm to 23.7 cm New, unused item. I bought it for my tempura pot, but the size didn't fit, so I've been storing it under the sink. Shipping will be in simple packaging via Mercari delivery.
