Blue Sky Thinker’s Set (TWSBI Cosmos + 15mL Ama-iro + TC Passport Notebook 005)
The 2025 Blue Sky bundle set for blue sky thinking. Limited Edition TWSBI Eco Cosmos Blue with onyx coloured trim and nib, paired with Pilot Iroshizuku Ama-iro Fountain Pen Ink and a Traveler’s Co passport size (80 pages) containing a Japanese lightweight paper, to really show off the full depth of your ink.
Uncapping Cosmos feels like unlocking a mini universe, where every line you write suddenly carries more possibility. It’s more than a pen; it’s permission to trust your ideas, even the big ones.
TWSBI Eco combines simplicity and elegance in this very contemporary fountain pen. By using a piston ink-filling system, TWSBI has been able to create a fountain pen with very high ink capacity. What this means is that you no longer need ink cartridges or a converter...just fill this high capacity fountain pen and away you go.
Why use this pen? Smooth nibs made in Germany, a transparent barrel to show off your ink and a capacity that will have you writing for about a month before you need to refill. A great option for deep thinking, where you don’t really want to stop mid thought just to refill. Â
All parts are detachable for cleaning. Packaged in a gift box with spanner and grease for mechanism.
