This quick sketch of people relaxing under an olive tree in Rabin Square, Tel Aviv, was drawn entirely with a Tombow Fudenosuke Brush Pen – Double-Sided – Gray/Black, which is a hard, durable (for a brush pen), waterproof brush pen which has become a staple in my drawing kit. Highly recommended, especially if you’re new to brush pens, or plan to use them with watercolours.
