Granatex GTX 701 Print

Granatex 701 consists only of the pigment color chips used in Granatex 700. Manufacturers add solid surface quality ATH as a substitute for the Granatex 700 processed background material. The result is a material that approximates the high quality of Granatex 700, our top-of-the-line granite filler material.
