19807 White of the Whale 1 oz

I’ve been using it for white-on-dark sketching and the water resistance is a lifesaver—once it dries, it stays put even when I accidentally spill coffee on the page. The 1 oz bottle is small but lasts a while since a little goes a long way.

The fluorescent glow is subtle but real under a blacklight, and it layers over dark paper better than I expected for a white ink. It dries to a tough, waterproof finish that hasn’t budged under a few spills on my sketchbook.

My first test page came out streaky, but after letting it settle and shaking the bottle properly, the white lays down surprisingly smooth and even on dark paper. It’s genuinely waterproof once dry, which I appreciate since I tend to smudge everything.
