Tombow was established in 1913 in Tokyo, when Japan was still building its industrial identity. Founded by Harunosuke Ogawa, the company aimed to create a Japanese pencil that could stand alongside the best in the world. Over decades, it refined graphite, wood, and manufacturing with a focus on patience and precision rather than speed.
This approach led to the MONO 100 series in 1967. The Tombow MONO 100 12-pencil set gathers a full range of grades, designed for control and flexibility. Each pencil uses an ultra-fine graphite structure with up to 10 billion particles per cubic centimeter, delivering smooth, consistent, and precise lines.
MONO 100 is a tool for professionals, artists, architects, and designers who rely on accuracy in every stroke. Built from premium cedar wood with perfect balance, it offers a natural, controlled drawing experience shaped by Japanese craftsmanship and attention to detail.

Despite ordering internationally, their team made the entire experience feel personal and genuinely appreciated. The attention to detail and the hand written note, lovely!
The pen itself is exceptional. It writes like it punches well above its weight class and has genuinely changed the way I look at modern fountain pens. An outstanding writing instrument backed by equally outstanding customer service. Highly recommended!
