ITEM INFO Item introduction

The defining features of "Cooler Shock" are its excellent cooling power and ease of use!
It boasts amazingly impressive cooling power and durability,
It's an essential item to keep in your cooler box when camping or outdoors.
In everyday life, it's great to carry in your lunch bag or when shopping at the supermarket.
Also, keeping it in your freezer is a great way to prepare for emergencies like sudden power outages.
Available in three sizes: Small, Medium, and Large.
Available individually or in sets (S x 5 pcs, M x 4 pcs, L x 3 pcs),
Choose the perfect one for your needs from our wide variety of options.



This Large size provides excellent cooling even in large cooler boxes.
Although it is large, it is thin and not bulky, and can be placed in the gaps between ingredients to make efficient use of space.
(Estimated cooling time: Using two packs, one pack will keep a 15L cooler box cool for one day, using two packs will keep a 90L cooler box cool for two days,
Using three packs will keep a 90L cooler box cool for half a day.)
Using multiple packs increases the cooling power, making it compatible with cooler boxes of various sizes.


■Outstanding cooling power■
"Cooler Shock" is designed to maintain a temperature of -7.8°C for long periods of time.
The temperature of both ice and ice packs (ice packs) including Cooler Shock
starts at the freezer temperature (0 to -12.2°C), and begins to rise once removed from the freezer.
Ice heats up quickly, hitting 0°C and eventually melting, but
"Cooler Shock" is designed to maintain a temperature of -7.8°C,
It can maintain the coldness inside your cooler box for a long time.
If you place several in your cooler box, it can maintain the same cooling power as a refrigerator for one to one and a half days.

■Compact & Slim Design■
"Cooler Shock" is a slim ice pack, approximately 2.5 to just under 4cm thick.
It takes up little space in your cooler box, fitting neatly between food and drinks for efficient cooling.
Compared to ice, much less is needed to achieve the same cooling power, and it weighs less too.
The exterior is made of a three-layer structure consisting of aluminum, which has excellent thermal conductivity, polyethylene, and nylon, which offer excellent rigidity.
At just about 0.2mm thick, the pack efficiently releases the cold inside, keeping things cold for long periods of time.
Another benefit is that it doesn't get in the way when pre-cooling inside the freezer.

■Short Pre-Cooling Time■
Another advantage is that the pre-cooling time (the time it takes for the ice pack to freeze) is short, even compared to a certain hard-type ice pack that has a high cooling effect.
If you place it in the freezer the night before you want to use it, it's ready to use the next day.
(For reference: A certain hard-type ice pack takes more than two days to pre-cool, and even a double-speed freezing type takes about one day.)
Of course, the cooling effect also far exceeds that of conventional ice packs,
It has been proven that it maintains its high cooling power even after a long time.

■Unbelievable Ease of Use■
Cooler Shock is compact, has excellent cooling power, and is available in a wide range of sizes.
Both soft and hard cooler boxes offer excellent cooling power.
You can safely store food for long periods of time, even when camping in the middle of summer.
By placing it in the gap between cans, you can enjoy ice-cold drinks outdoors, even in the summer.

[Large] For a full-size cooler box,
(If you're using a larger cooler box or want to keep food cold for a long time, use multiple units together.)



"Cooler Shock" is a great product that solves all the problems you've had with conventional ice packs: "weak cooling power," "melts quickly,"
"takes too long to pre-cool, so you can't use it when you need it," and "takes up too much space in the freezer or cooler box, making it difficult to fit food in."
Another great feature is that you can dramatically improve the functionality of your existing cooler box without having to replace it!
The wide range of sizes not found in Japanese products is also a plus,
It's perfect for all sorts of occasions, from light use to serious outdoor activities.
