GEL-COOL Square W 500ml x 2 Tiers

Largest capacity model in the GEL-COOL series. This model consists of two L-size lunchboxes stacked on top of each other, recommended for those who want to eat a lot. By reversing the direction of the rubber band, it can also be used as a single-layer model. Both the upper and lower tiers are equipped with a cold-insulating lid, but the lower tier can also be used without the lid. In 2023, the product was renewed for easier use. [Renewal points] The inner surface has been treated with a patented "rakushibo" finish, making it less likely to get dirty and less likely to show scratches. The outer surface has been changed from a glossy finish to a more elegant matte finish. [About GEL-COOL] GEL-COOL has a 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 keep for about 4 hours at an outside temperature of 25 ℃. *It is said that bacteria become more active at temperatures above 25℃.
