Here at the letterbox shop we have refined our products to find the best possible way to make our products keep their quality for the life of the product. In 2016 the letterbox shop purchased its own Fiber Laser Cutting Machine and moved all its products away from engraving or etching of the metals as these methods may have issues with longevity, we now individually custom laser cut each order as its manufactured. This is where the laser machine completely cuts through the metal and then we back the panel with a contrasting acrylic or coloured metal to highlight the text or number.
