This is a used item. I don't remember using it many times, but it has stains and rust due to long-term storage, so please check the photos. Moka Pot Circle 80mm Moka Pot Circle Auxiliary Trivet Sub-Trivet Mini Trivet Sierra Cup Single Burner Product Name: Moka Pot Circle Dimensions: Outer diameter 80mm, Height approx. 2.5mm, Plate thickness 0.8mm Material: Stainless steel SUS430 2B Country of Origin: Japan The Moka Pot Circle is an auxiliary trivet for direct-flame espresso makers. It allows you to stably place items like a Sierra cup with a small bottom, which wouldn't fit on a regular large trivet. It has 12 grooves that fit the legs of various types of trivets. It's very light, making it convenient to carry outdoors. It's small and thin, so it doesn't take up much storage space. The height is approximately 2.5mm. It uses heat-resistant stainless steel SUS430.
