bolingop50 Four-colors Gravity Pen: Multifunctional design
Available Options

The Four-colors Gravity Pen isn't just another writing instrument—it's a clever little gadget that feels like it's from the future. By flipping the pen, you switch colors, thanks to its built-in gravity sensor. No more fumbling with four separate pens or clicking through a rainbow of options. It's all in the wrist, and the 0.5mm lead core keeps your lines sharp, whether you're jotting down lecture notes or signing a contract.
But here's the kicker: the roller ball mechanism isn't just for show. It delivers a buttery smooth ink flow that won't quit, even during marathon brainstorming sessions. The grip? Designed to keep your hand from staging a protest after the third hour of use. For students buried in textbooks or professionals drowning in paperwork, this pen isn't just handy—it's a tiny revolution in your pocket.
