These Postalco notebooks totally nail it. The critical issue of binding has been resolved once and for all with both a spiral and a spine. The covers are bonded with starched & pressed water-resistant cotton in a lovely rainbow of colors: brown, school bus yellow, dark green, signal red, light blue, and dark blue. And the paper inside is ecologically made, chlorine-free, and printed with a 1mm pin-graph, so that you’re 100% straight—up, down, and sideways.
The medium size is quite reasonable. It’s a bit big for your pocket, but works wonders in your tote bag.
