Wearable miniature cooler/warmer

You may now cool or heat a small part of your body on the go, if you are in Japan and have 13000 to blow. The Reon Pocket is a roughly the size of a smartphone, hangs around your neck, and claims to cool that spot up to 13C or warm it 8.3C. As you can see from the photo, a special shirt will come with it so that it can be perfectly seated.
