Description Opa Locka New England Slate is a two part system with both an A piece and a B Piece. The purpose of multiple tools in a set is to open up the pattern so the eye does not see repetition. Each piece has slight variations in the texture for a more random look. New England Slate is the background texture. Also check out our line of Ashlar Slates for a similar pattern with a large selection of background textures. Stamp size 24″ X 36″. Package savings reflected in price.
