Monami 153 Side-Click Ballpoint Pen

This practical, retro-styled ballpoint from South Korea features a retract/extend mechanism that doubles as a satisfying little fidget. Press the button on the back to extend the tip; then, when you're done writing, press the side button to retract it again. It makes a nice little "snap" sound in both directions. Inside the pen, you've got a classic ballpoint cartridge with a 1.0 mm tip — perfect for ordinary writing on all kinds of paper, including cheap office paper and carbon paper. Sold individually.
