We use the thickest V-FS A3 paper, a high-quality printing paper that achieves a high-level balance between the opposing properties of excellent color development and paper texture, and is also FSC certified*. Due to its thickness, it is less susceptible to humidity and environmental changes, and is characterized by its resistance to curling and warping.

*FSC certification evaluates and certifies "whether forest management and logging are carried out with consideration for the environment and local communities," and certifies that products are derived from such forests (products made from properly managed forest timber). The operation is carried out by the FSC (Forest Stewardship Council®, headquartered in Germany), an NGO.
