Thank you for viewing my listing among many others. This is a set of 2 slim neck coolers with cooling pouches! As the temperature rises in the Japanese summer, just going outside for a bit can make you feel like you're suffering from heatstroke... This is an essential item perfect for the Japanese summer! However, there are many products like this, but don't they stop being cold quickly?? This comes with a cooling pouch, so you can use it to stay cool even when you're out and about! That's what makes this product recommended! Also, its slim design makes it discreet and easy to use! For those who work outdoors in the summer, play sports, love the outdoors, or enjoy going out, this is a product that we want everyone to use, not just those specific groups. That's how dangerous the Japanese summer is...
