This shade of pea soup green is officially the best color for notebooks. Bonus, the super-smooth paper inside is a treat for writing, it lays nice n' flat when open, and its unique grid/lined hybrid paper makes for massive adaptability.
If there's a smaller grid notebook out there, we certainly haven't seen such a thing in Kansas. I mean think about it. A millimeter is barely anything and this is just two times that. VERY SMALL GRID, YA HEAR?
