Simple and eco-friendly lunch box with a cold storage function

The L size is perfect for everyday use; we also recommend using the S size (220ml) and onigiri case together.

This series superimposes the cold image of GEL-COOL, whose lid serves as a refrigerant, on Italian gelato. The colors are not too cute and have a subdued tone, making them suitable for people of all ages.

By mixing powdered Hokkaido scallop shells into some of the materials, the amount of plastic used has been reduced, making this an environmentally friendly product.

In 2023, the product was renewed to make it easier to use. [Points of renewal] The inner surface is coated with a patented "rakushibo" finish, which prevents stains and scratches from showing through. The outer surface has been changed from a glossy finish to a more elegant matte finish.

[About GEL-COOL]
GEL-COOL has special technology to seal a refrigerant inside the lid, and the entire lid is frozen in a refrigerator. In other words, the lid becomes a refrigerant. This makes perfect sense because cold air flows from the top down. It is also easy to use. When you are done eating, simply wash it and store the lid in the freezer. When you are ready to use it, just take it out of the freezer and put the lid on the lunch box, and you are good to go. Even on warm days, you can take it with you without worry. You will never forget to put in the coolant, and you can use it over and over again. If you remove the lid, you can also put it in the microwave.

GEL-COOL helps you enjoy a comfortable lunch box life, freeing you from the worry of food poisoning and the stress of daily use of refrigerant.

[Standard for cooling effect (15℃ or lower)]
When food chilled in a refrigerator (5 ℃) is placed in the container, it will stay cold for about 4 hours at an outside temperature of 25 ℃. *It is said that bacteria become more active at temperatures above 25°C.
