The Prime Art Gallery Black Canvas 18x24 Inches delivers a dramatic, deep black foundation meticulously triple-primed to make neon acrylics, metallic inks, and rich oil colors pop with incredible contrast. Its heavy-duty 380gsm profile is built from 100% pure cotton canvas stretched over a substantial 37mm deep gallery wooden frame that prevents any bending or warping. Featuring a clean, staple-free splined finish on the back, this premium 457mm x 610mm surface allows artists to paint all the way around the edges for a frame-free, modern gallery presentation.
