Stone Edge Surfaces European Field Stone decorative concrete stamp set for Stamped Concrete, Decorative Concrete, Concrete Overlay. The European Field Stone stamp set comes as a set of 4 stamps. The stamps have an incredible rough European cut random stone size wall pattern, with each stamp having two handles for application control. The 4 stamps can fit randomly together with each stamp being approximately 204″x24″ in size and meant to rotate 180 degrees to double the pattern, so 4 stamps can give 8 looks.
