Our stone paper is ecological, composed of 75% calcium carbonate and 25% binder, including resin and polyethylene. Protected by the Polish Patent Office, the paper composition produces a high-quality material. The addition of calcium makes the surface naturally white, smooth, and velvety. More importantly, stone paper is highly tear-resistant and moisture-proof. In case of accidental spills, e.g. water or tea, the notes do not smudge and the paper is still writeable.
