YUPO gives visual artists an amazingly beautiful canvas to work with. Its bright white, smooth finish gives artists the flexibility to work in several different mediums to achieve unique and creative results. Painting or drawing on the ultra-smooth surface of YUPO is different than regular watercolour or drawing paper, and will require some adjustments by the artist. The surface may be wiped clean to restore the original white of the sheet, making it an excellent surface for beginners. YUPO® is also a very exciting substrate for more advanced and experimental artists. Its creative possibilities and suitable applications are infinite. 100% Polyprolyene pad. 390gsm Neutral pH sheets with smooth surface. Great for various watercolor techniques. Made in USA. Includes 10 strong waterproof sheets. Measurements: 9 x 12 inches.
