19804 Lex Gray（防彈系列）4.5 盎司

The bottle is huge for the price, and the ink holds up perfectly when I spill water on my desk. It dries a nice neutral gray that stays put on the page without any smear.

Wrote a few pages of notes in my journal, left it in a bag during a downpour, and every single word stayed perfectly legible. The archival quality is no joke — this ink isn't going anywhere, which is exactly what I wanted for long-term documents.

The bottle is huge for the price, so I'm set for years. I tested a splatter under running water and the lines didn't budge, which is exactly the bulletproof behavior I needed for signing documents.
