The paper showdown is here.
Have you ever wondered what the real difference is between the iconic 52gsm Tomoe River Paper and 83gsm Cosmo Air?
We’re breaking it down.
52gsm Tomoe River Paper (TRP):
The legendary original.
This paper is incredibly thin, lightweight, and almost translucent, famous for its satisfying crinkle. It’s the master of showing off ink properties, making sheen and shading pop like no other.
It’s for the purist who loves a sensory writing experience.
83gsm Cosmo Air Paper:
The modern powerhouse.
This paper is thicker, opaquer, and has a velvety-smooth texture with just a hint of feedback. Colors appear nicely saturated and vibrant on its surface.
Due to its thickness, it has significantly less ghosting, making it a fantastic choice for those who love using heavy inks, markers, or even light watercolor.
So, which paper is in which 2026 product? We’re giving you the choice!
If you're team Cosmo Air for that vibrant, sturdy feel, you'll love our Core Planner and Dated Inserts.
If you're a classic Tomoe River fan who lives for that sheen and crinkle, our Common Planner and Booklets are for you.
Also here's the full lineup, in order, from our ink test:
- Sailor Pigment Ink Souboku (Blue Ink)
- De Atramentis Document Ink Black
- Diamine Ink Ancient Copper
- Poussiere De Lune Herbin Ink
