The 17 cm x 13 cm piece of slate is suitable for a house number. The Plaque is made from high quality slightly riven 12mm thick natural slate, paint filled with a choice of 5 colours (or can be left natural). It is then finished with natural oils, pre-drilled and supplied with screws, screwcaps and wall plugs. I can usually engrave the slate with most fonts but will use Times New Roman as all numbers photo unless requested otherwise. Please note slate is a natural product and every piece is different, markings and colour may vary slightly.
