The 2+1 Slim from Pilot is another multi-pen that just doesn't want to look like one. It features a 0.7 mm black ballpoint pen, a 0.7 mm red ballpoint pen, and a 0.5 mm mechanical pencil. The name of each is lightly printed on the barrel. Just hold the pen horizontally with the desired instrument name facing upward and click. Internal weight mechanisms change the pen setting automatically! Press the side button on the clip to swiftly retract the instrument into the barrel.
Pen dimensions: Approximately 13.5 cm long, and 8 mm in diameter.
