The Inka Pen is both a keychain and a pen, making it better than a normal pen and definitely way better than a normal keychain. We've all seen those space pens when we were kids that allowed us to write upside down. The novelty quickly wore out, and those pens were soon lost or misplaced—who needs to write upside-down anyway? Well the Inka Pen, with its pressurized ink cartridge, lets you write in below-zero temperatures, in the desert, or even when it's wet. Really? When it's wet? Wouldn't the paper disintegrate before you're finished writing down whatever it is you're writing?
In any case, if anyone needs to be able to write anywhere, this is available now for $25.
