* Mr. Pen canvas panels come in a 5-pack with assorted sizes to accommodate a variety of artistic projects, allowing for flexibility and experimentation in painting. * Each canvas is pre-primed with acid-free acrylic gesso, making them ready to use right out of the package and suitable for both amateur and professional artists. * The panels are ideal for a wide range of mediums, including oil, acrylic, watercolor, and tempera, providing a reliable surface for different painting techniques. * Built with durability in mind, the canvases are mounted on sturdy board, ensuring they remain flat during the painting process and while on display. * The canvas surface is smooth and tightly stretched to prevent sagging, offering a consistent texture that artists can depend on for detailed work.
