Bút bi lăn TornadoTM Acrylic Cosmic Swirl Xanh & Trắng

The acrylic barrel has this deep, glossy swirl that shifts between green and white depending on the light, so it’s genuinely fun just to look at while I write. It’s a rollerball, so the ink flows smoothly and the grip isn’t slippery at all. Took me back to that late-60s vibe without feeling kitschy.

The psychedelic green-and-white swirl pattern on the barrel is way more vivid in person than in the photos, and the rollerball glides across paper with barely any pressure needed. I've been using it daily for a week now, and the ink flow stays consistent without skipping or smearing.

The acrylic barrel has this smooth, weighty feel that makes the psychedelic green and white swirl look even better in person than on screen. The rollerball glides effortlessly across paper, no skipping or blotting even on cheap notepads.
