Product Review

Made of durable nylon and carbon fiber that's tough, lightweight, and corrosion-resistant, one end of the Inka Mobile features a carabiner clip that securely anchors to a key ring, zipper pull, or nearly any loop or D-ring, so you can always know where the pen is when you need it. Release the pen from the clip with a couple of quick twists-its replaceable pressurized cartridge contains blue waterproof ink that writes smoothly and consistently in extreme temperatures, upside-down, at any altitude - even underwater. And to add to its versatility, the cap at the opposite end of the Inka Mobile opens to reveal an easily accessible touch-screen stylus - perfect for everything from quick notes to business presentations.
