I believe this is a product from Heiwa Freiz. Teflon, used item. I used this on a gas stove during the period in 2024 when I hadn't finished unpacking after moving. With these two items, I realized that I could cook rice, stir-fry, simmer, make boiled eggs, boil water, and do some light sauteing. After unpacking, I've been using the cookware I'm used to, so even though there are scratches, I subjectively don't think there's much damage. The two-handled pot is 22cm. The single-handled pot is 16cm. Both have glass lids. The orange color brightened up the kitchen. For gas stoves.
