This is a set of Ice Japan's Aibo (Love Hat) for 4 hours. I received it on Mercari in December 2025. The previous owner had used it for six months. I used it for about three months. I received a set for 5 hours. During the previous owner's use, one of the head cotton cooling gel white gels (the three light green ones) was damaged and discarded. Therefore, there are 4 head cotton cooling gel white gels, and 5 sets of the others. Also, one of the 4 head cotton cooling gel white gels has a small tear and has tape on it (see photo 2). There was no problem with use, but please be aware of this. The cooler box handle cannot be fully stored (see photo 3). There was no problem with use, but please be aware of this. I will include the instruction manual, but please check Ice Japan's YouTube for detailed usage instructions. As a bonus, I will include two ice beanies (see photo 4). On the way home, the Aibo was heavy, so I froze the ice beanies and wore them on the way home. 〈Set Contents〉 ・Insulated hold cap (black) x 1 ・Coolant holder support cap (light blue) x 5 ・Coolant set x 5 (only 4 head cotton cooling gel white gels) ・Cooler box -10℃ coolant x 7 ・Cooler box (Coleman) x 1 ・Ice beanie x 2 ・Instruction manual Items that can be washed were washed in the washing machine, and those that cannot be washed were wiped with disinfectant wipes.
