Necessary for fine art, hobby or craft constructions, foamcore is used for everything from mounting photos to building models. Solid black--to the core--means edges do not have to be hidden for a professional look. The deep, rich, black color gives projects a striking appearance, making them stand out from the rest. Alvin’s black foamcore sheets are easy to use and cut cleanly. The edges spring back to their original height when cut. These boards are a large 30” X 40” size and 1/2" thick, and can easily be cut down to a smaller size if needed. This package contains 25 sheets of black foam board. Total weight for these boards is 46 lbs - $27.50 for oversize shipping costs.
