19087 Kung te-Cheng

I’ve been using this ink for daily journaling for three weeks now, and the bulletproof formula holds up beautifully—even a splash of water on the page didn’t smudge a single line. The 3 oz bottle is plenty generous for the price, and I love that my notes will stay archival for years.

The archival rating on this bottle is no joke — I've left it on a page for two weeks and it hasn't budged even when I wiped with a wet cloth. The 3 oz size feels generous too, so I don't have to ration my daily notes.

Used this in my daily planner and the ink stays put even when I accidentally spilled coffee on the page. The bulletproof formula is no joke—three weeks later, the writing hasn't faded or bled through. Also, the 3 oz bottle is a solid size that'll last me a while.
