A children's neck cooler that cools down simply by soaking it in water. - Brand: MAGICOOL - Colors: Mizuiro (water color), Light Blue - Size: For children - Features: Cooling effect just by soaking in water - Material: 100% Cotton I've been using it for my first-grade son, and he's able to use it well. He seems to prefer it because the coolness lasts longer than a hard neck cooler (*^^*) I have two in stock, so you can purchase them as a set.
