This is a sealable, heat-resistant glass container. I'm selling it because I underestimated the space in my refrigerator and bought too many. I'm listing it as new because I haven't taken it out of the box except to take pictures. It's a large size, but it has a very user-friendly design and is very useful. Currently on Amazon, the 700ml size is around 1600 yen, and the 1.5l size is around 2700 yen. - Brand: iwaki - Model Name: PACK & RANGE - Features: Sealable glass container - Sizes: 700ml, 1.5l - Heat resistance: 120℃
