Tools on Yukito's desk.
The electric pencil sharpener is a vintage machine from my first year of the elementary school, and is still active. The Microman figure standing aside is used as a posing doll for sketch.
The 5 pens I currently use are 2 old and new G pens, 2 old and new crow quills, and Tachikawa's Japanese character pen.
Rulers are bulky and if you handle them roughly, their edges could break off. It's difficult to store them conveniently, so I made a ruler stand by myself.
