Cute little pea mosquito repellent strap.

This cute little smiling pea in a pod is actually a mosquito repellent that works for up to 6 hours straight. Just put one droplet of the peppermint-ish extract that comes with it into the little guy's back, clip it onto your backpack, belt, cell phone, or briefcase, and you won't get bitten by mosquitos. Don't rely on this alone if you're going into the villages of India or the jungles of Malaysia, though. You'll need 100% DEET and malaria pills there. This is just for little excursions in cities where mosquitos don't kill people, like Tokyo or San Francisco. Available here for 500 yen.
