I'm a giant fan of grid notebooks. Late last year, I picked up a Hobonichi Planner and really loved the ultra-thin Tomoe River paper that still withstood fountain pen inks.
I've been looking for a notebook with the same paper type in a grid layout with a large page count, and this notebook doesn't disappoint. The company is Nanami Paper, a small business run in Southern California and these notebooks are wonderful. They also come in lined and blank options if those are more of your style.
The Crossfield variant restocked about two weeks ago and has been selling out on and off depending on when stock is replenished manually. Hope everyone here likes it as much as I do!
