These natural Pennsylvania flagstones are tumbled to achieve semi-smooth edges and sides. Each stone is unique but typically measures 11-14 inches in length, ¾ to 1 inch thick and weighs between 10 to 15 pounds. Each stone includes an image you select and can be personalized with 3 lines of text. Your message is engraved onto the stone and then colored with black acrylic stain. This stain is resistant to chipping or fading, so your message will remain year after year.
