These natural Pennsylvania flagstones are tumbled to achieve semi-smooth edges and sides. Each stone is unique and different but typically measure 12-18 inches in length, 1 ½-2 inches thick and weigh between 15-30 pounds. Each stone will include an image you select and can be personalized with up to 3 lines of text. Your message is engraved into 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.
