Yupo is machine-made in the USA and recyclable. As a watercolor paper,  it has the advantage of being non-absorbent so colors lie on top of its  surface producing brilliant, vibrant effects. Colors retain their true  clarity and brilliance. Yupo requires no soaking, stretching, or taping  flat. Best of all, it allows you to wipe off unwanted sections of your  painting and start again with a fresh surface.
