The Tombow Mono 100 Pencil was released in 1967 to commemorate Tombow’s 55th anniversary and as a direct competitor to the Mitsubishi Hi-Uni. Because the original Mono pencil was such a huge success in Japan, Tombow began releasing many different products with the Mono name – such as the Tombow Mono Eraser.
What makes the Mono 100 so special is that the core particles were increased to 10 billion particles per cubic millimeter. This high-density structure of the graphite lead allows for smooth and dark lines. After it was released, it was considered a high-quality, luxury pencil and was sought after by kids and adults alike.
- Black body with gold gilded accents and painted dipped end
- Full line of hardnesses from 10H to 10B
Tombow Pencil Co., Ltd. was established in Japan in 1913 as a manufacturer of wood-cased lead and colored pencils. It is not an exaggeration to say that every student in Japan has grown up with the Tombow pencil.
During the past four decades, Tombow has diversified its manufacturing program to include ballpoint pens, roller ball pens, markers, correction tape, glue sticks, liquid glues, adhesive tape, and dry highlighters. Today, Tombow has achieved an outstanding reputation for its unique, innovative and original products.
