Black Ink - Thai Reversible Unryu Paper - Purple Red - 24x35in. - Stronger and more durable then the single unryu, these reversible papers are created by hand-laminating and crumbling two contrasting sheets of unryu with a neutral polyvinyl acetate-based adhesive. This process gives the paper a coarse texture and adds weight to the sheet. When wet, this paper has a great deal of elasticity. An excellent paper for bookbinding, boxmaking, frames, and decorative projects.
