Standard (Bainbridge & Crescent) quality paper mats are pH neutral. These boards are treated to slow down the breakdown that naturally occurs with any wood pulp product. A pH neutral mat will enhance your artwork for a number of years, but eventually will fade and may cause acid stains where the mat touches the art. Standard pH neutral mats are not archival, 4ply (1/16”)

No minimum for PICK UP orders.

Perfect for General Framing, Open Edition Reproductions, and Posters
