Just a few sketches of the tools I use:

Maruman SS2 sketch book. I have used this sketchbook for over 10 years. I love the creamy paper. Use it not only for sketches but as a scrapbook as well. 

For most of my sketches I start with the Staedler pencil, and retrace with an ink pen. The drawings here were made with a 03 UNI Pen which has water proof and fade proof pigment ink. It’s maybe a bit thin, but is pretty good for hatching as well. I like to keep my text in red using the same UNI 03 pen but then in red. The key to pens is how they feel on the paper.

Shadowing is done with a Warm Grey 2 Copic marker. I use Tombow highlight markers in blue, green and yellow for any colouring. Sporadicly I use other Copic marker colours for some additional colouring.

Other tools are post-it notes (generic ones, not 3M) a scale ruler (150mm, not 1500 as I wrote in the drawing), Tombow glue stick and a Staedler 502 pen sharpener.
