Ambiance Studio Wood Frames are perfect for framing papers, panels, posters, and certificates. These professional quality wood frames are finished with three coats of urethane, which is UV cured, two electrostatic coats, and a final UV cured finish. The finish is applied to the wood and hardened via a chemical reaction triggered by ultraviolet light. The UV process ensures a brilliant smooth finish that is more durable than other frame finishes on the market. Each frame comes with a sheet of optically clear glazing and rigid MDF backing board. D-ring hangers are already attached to the high-density backing board, so you don't need to worry about attaching hardware to the frame. A 90 day warranty is included on all of our products to ensure your satisfaction.
