Purchased in October 2025. I'm selling it because it was too small. A lunch cross that keeps things cool is also included. It doesn't need to be tied, so even children can wrap it. Used once after purchase. At that time, I put in rice balls wrapped in plastic wrap and a small amount of side dishes using food cups. Snack box: 1980 yen Cross: 1290 yen Snack box. I think there are many uses, such as for baby food or snacks for children. It's easy to open and close and easy to wash.
