Maintain the organization of your documents and files with the Stone Paper Document Folder. This folder is crafted from stone paper, a robust and enduring paper-like material made from calcium carbonate combined with high-density polyethylene (HDPE) resin. Thanks to its unique composition, stone paper is waterproof, grease-resistant, and easily washable. The folder's surface accommodates writing with pencils or ballpoint pens, just like conventional paper.
