Optimizing the luggage is a never ending task. I do it with pleasure and it gives me great results and a new way of traveling. Regarding the writing tools I remember the days, before discovering so many fountain pens and inks, when all was easier.
There are some requirements: Full performance, simple and light. I can carry everything with me in any moment and in everywhere. "My atelier is the real world"
Currently I use the following items:
-My handmade notebook.
-MUJI passport notebook for fast notes.
-"Happy Every Day" case. I found it in 7 Eleven in Bangkok.
-Two tiny kits of watercolors.
-Two Stabilo markers: orange and turquoise.
-TWSBI 580 EF fountain pen.
-Two Lamy fountain pens.
-Preppy fountain pen.
-Kaweco fountain pen.
-Two disposable Zebra brushes.
-Pigma Micron 005.
-Rotring mechanical pencil.
-Rotring Isograph 0,10.
-Rotring Isograph 0,18.
-Airmail masking tape.
-Tiny pencil sand color.
Together with this I carry another case with spares of some of the pens, glue and inks for fountain pens.
