This solid wood growth chart comes with 3D numbers in your choice of black or white. Hanging hardware included on the back. Tick marks are done with professional paint pens in the same colour as the numbers. Purchase a variety of individual acrylic images to be able to offer you customers. All Growth Charts are sealed with a clear protectant. Please note that it does not have a glossy finish or feel and is absorbed into the chart for durability and longevity. Comes with a saw tooth hanger on the back for easy hanging. Our charts START at 6" as they are meant to hand 6" off the floor to accommodate the average baseboard. Wood is a natural product, each piece WILL have varying knots and imperfections.
