This foam board set includes 12 white foam core boards designed for mounting, crafts, paintings, prints, displays, presentations, and projects. Each board features a smooth double-sided surface and a 3/16" thick seep-proof design that helps prevent paint from soaking through. The acid-free construction helps preserve color vibrancy over time. These boards are easy to cut with a utility knife for precise custom shapes and model work. Sized at 24 x 36", they fit standard frames and support extended creative projects.
