EcoNan Series Popularity Ranking

Made from high-quality paper, this type offers the most authentic paper feel. Frequently used in scenarios involving drawing, coloring, or handwriting.

3rd: Banana Paper Type

Made with fiber from organic banana tree stems sourced in Zambia, contributing to fair trade and climate-positive initiatives. Utilizes Echizen washi paper techniques, resulting in a soft, fluffy texture.

Popular Non-EcoNan File Options

Kousoku Offset offers several non-plastic file alternatives beyond the EcoNan series.
