Stronger and more durable than single unryu, the Reversible Black & Red paper is created by hand-laminating and crumpling 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. It is an excellent paper for bookbinding, boxmaking, book art, frames, and decorative projects.
