New, unused summer ice packs. Strong, rapid freezing for long periods, long-lasting cooling, and comes with a dedicated cooling cover. Set of 2.

If you need long-lasting cold retention, this ice pack is all you need. Simply freeze it to achieve a powerful sub-zero temperature of -18°C. Your drinks and food will be refreshingly chilled in no time. Furthermore, when used with a cooler bag even in the midsummer outdoors, the cooling effect can last for up to 12 hours. It reliably keeps your lunch drinks, after-work beers, and cooler box contents fresh and delicious.

This ice pack for bento boxes features a compact design, measuring 19.2cm in height, 11.8cm in width, and a mere 3cm in thickness. It's slightly larger than a smartphone and weighs approximately 580g, making it lightweight and convenient to carry. It fits neatly into your work bag, car storage, sports bag, cooler box, and more. The opening features a completely sealed structure that closes securely, so you don't have to worry about water leakage during transport or daily use. Additionally, a dedicated insulated cover for the ice pack is included. This not only helps to prolong the cooling effect but also prevents the ice pack from coming into direct contact with fruits and vegetables, preventing them from freezing or spoiling. We promise more peace of mind and meticulous freshness preservation.

This long-lasting, powerful ice pack thoroughly solves the issues of previous products. In older models, repeated freezing and thawing could cause the outer casing to deform due to thermal expansion and contraction, shortening its lifespan. This product has been improved in this regard with a fully reinforced outer casing. By adopting a thicker, stronger material and structure, it not only offers excellent impact resistance but also prevents deformation from the root cause. It has passed rigorous drop and durability tests, maintaining its shape even after long-term use. Furthermore, the outer casing is made of food-grade polyethylene material and has an antibacterial coating on the surface. This ensures double protection for hygiene and safety, even when in direct contact with food. The tough material withstands repeated use, not only leading to cost savings but also contributing to the reduction of plastic waste.

This strongest ice pack uses an environmentally friendly and safe polymer gel phase change material inside. Compared to previous products, it freezes faster and has higher freezing efficiency. It quickly responds to various situations, from keeping your daily lunch cool during commutes to school, to cooling down after picnics, camping, outdoor events, and even emergency cooling during disasters, providing long-lasting cold retention. When used in conjunction with a cooler bag or cooler box, even greater cooling effects can be expected.
