Price is not negotiable. GEL-COOL triangle onigiri (rice ball) case 180ml capacity, perfect for carrying. New, unused, gray color. I'm selling it because I don't use it. "I want my children to eat lunch without worrying about food poisoning even in the summer" - this parental concern was the inspiration for the "GEL-COOL" lunch box, which integrates a cold pack with the lid. The lid has a cold pack sealed inside using a special technology, and you freeze the entire lid in the freezer before use. The size is just right for one convenience store onigiri. It opens and closes with one touch, and the lid has a cooling function. The hard case also prevents the onigiri from being crushed. - Brand: GEL-COOL - Model Name: Triangle Onigiri Case - Size: 10.3cm x 9.5cm x 6.6cm - Capacity: 180ml - How to use: Just set the frozen lid 9 Thank you for looking.
