12 Pack 20x20cm Canvas Panels: Includes 12 blank canvas panels, each measuring 20 x 20cm with 3mm thickness. A practical square size for acrylic painting, oil painting, craft projects, art practice and home décor. 100% Cotton, 280gsm Medium Grain Surface: Made with 100% cotton canvas and 280gsm fabric weight. The medium grain texture gives a balanced painting surface with enough grip for colour layering, brush strokes and palette knife work. Triple Primed & Acid-Free: Triple gesso primed and acid-free to create a ready-to-paint surface. Helps improve paint adhesion, reduce paint seepage and keep colours looking bright on the canvas board. Strong Flat Canvas Board: Mounted on a sturdy 3mm board to help keep the canvas panel flat while painting, drying, storing or framing. Easier to handle than stretched canvas for small artworks and practice pieces. For Artists, Students & Beginners: Suitable for acrylic and oil painting, ideal for artists, hobby painters, students, beginners, art classes, craft sessions and DIY wall art. Not recommended for heavy fluid acrylic pouring, as excess liquid paint may cause warping.
