MONO Natural is an environmentally conscious version of Tombow’s classic MONO eraser, formulated with biomass-derived materials including scallop shell powder. Its natural ivory tone comes from the shell-based material, while maintaining the clean erasing performance expected from a standard MONO eraser.

At least 10% of the eraser body by weight is made from biomass-derived material, earning it Japan’s Biomass Mark certification. The protective paper sleeve also contains more than 50% recycled paper pulp, and the eraser is made without phthalates.
