Yes. Your art is safe with us. The neutral PH aka "acid free" composition throughout our 4 ply mats means that they are less susceptible to fading, yellowing, or breakdown over time. Matting your artwork under acid-free boards also ensures that the mats will not stain or damage the photographs underneath.
Our mats are high quality Larson-Juhl Arqadia in color Glacier, with a white core. They are produced in the UK.
