I'm going to start with something discouraging, but I don't know how well this will work. Ome... no, no, if you put in the rice, add the right amount of water, and can calculate how much it will expand when cooked, it should work! ...Though I'm saying this after failing with a regular rice cooker myself... φ Approximately 22cm. Approximately 19cm without the handle. Height: Approximately 15cm. There are scratches on the outside. The inside, where the lid directly touches, also has some scratches. In photos 7 and 8, it looks like the paint has dripped. This is also on the outside. Judging by the inside, it doesn't look like it's been used, but looking at the bottom, it has. The white streaks are probably from storage, but the black marks seem to be more than just scratches. The rice bowl was inside, so take it with you. Don't need the rice bowl? I don't need it either. If you're interested, please consider it.
