Thanko has come up with a mouse for those with sweaty palms. The 3-button device has a 2-inch fan built into the base. The USBCOOLM is 6 x 12.6 x 4cm, has an on/off switch and can be used by those who are left and right handers. Compatible with Windows, you can get one for ¥1,980 (~$18.00.) While we are not sure we need a cooler mouse, at the very least we expect is that it might clean off the crumbs we sometimes spill.
