The water resistance on this one is no joke—I spilled coffee on a page of notes and the ink didn't budge. The 3 oz bottle is generous too, so I'll be using this for a long while.

The fluorescent glow under a blacklight is wild—way more visible than I expected for a daily-use ink. It survived a coffee spill on my notes without smudging, and the waterproof claim actually holds up on cheap paper.

I’ve been looking for an ink that won’t wash away if a letter gets wet, and this one holds up completely—even the fluorescent tint stays visible after a soak. The 3 oz bottle is a solid size for daily use, and the bulletproof formula gives me real peace of mind for anything archival.
