Woody debris has become a subject of interest for me during lasts years forest studies (Waldtagebuch=Forest diary). It is a fascinating microcosmos of immmense importance for biologic diversity and thus for the stability of forests. Last weekend I had the opportunity to start a small sketch of an impressive old dead oak trunk at one of my favorite places in our woods. During the week heavy snow came back and I finished the sketch in complete white silence while big snow flakes were falling on my sketchbook pages. The Pentel Energel writer has become a favorite alternative to my usual ink pen and it did fine, even though the paper was moist (The refill I use is Pentel Energel LR7-A. 0.7 mm black). This pen writes a deep black to the very end of the refill and the tip glides very smoothly over the paper.
