Small but mighty: the World's smallest walkie-talkies
These are an incredibly tiny example of the 2 way walkie talkie, an ever-popular inclusion in the big boys' toys arena. With flexible antennas and tiny, robust handsets, they're so pocket-portable you'll find yourself taking them everywhere. These aren’t just walkie talkies for kids, grown ups will love them too. If you can't be bothered going downstairs to talk to your flatmate, then you'll decimate your mobile phone bill into the bargain as well.
They work up to 30m apart, and yes, batteries are included. Driving in convoy? Paintballing? In different aisles of the supermarket? Not a problem with these mini bad boys.
