Fast-drying, durable, and flexible when dry, Daler-Rowney Graduate Acrylics are a great value for the classroom, workshop, or home. The bright, strong, waterbased colors brush easily onto paper, primed board, and canvas. They won't smudge if water is spilled on the surface of the painting, and their strong colors assure that paintings last a long time. Best of all, paper and canvas coated with Graduate Acrylics can be loosely rolled and stored without fear of cracking. Daler-Rowney Graduate Acrylics contain no solvents, so they're safe for children to use. A unique valve mechanism on the squeezable pots minimizes waste, while stay-clean technology minimizes the mess!
