All of the slate for the signs are sourced from mines in the Lake District and crafted by a local family of stonemasons. A square slate sign has 2 inch numbers and is approximately 13cm x 11cm. They come pre drilled with one hole each side of the numbers. We can offer these in light green slate or black slate. As slate is a natural product colours may vary in shade slighly. Delivery can take up to a week for the slate signs as some are made to order
