The Vevor canvas panel set includes 32 white painting boards in multiple sizes for artists, students, kids, and hobbyists. Each panel features a tightly woven cotton canvas surface mounted to a 3 mm MDF board for stability and reliable color absorption. The panels come pre-treated with triple layers of gesso, so they are ready to use right out of the package. Suitable for acrylics, oils, watercolors, sketches, and paint markers, this set supports a wide range of art projects.
