Per the maker’s website, PaperStone® is an ecofriendly material that is produced in a socially responsible manner. It is also strong and tough. It has steel-like strength in span, stone-like beauty and it can be worked like hardwoods. PaperStone® is NSF certified as safe for direct food contact. It is available in a broad variety of colors. At present, I am using three – Azure, Pewter and, for you wine lovers, Cabernet. Our Marine Band Combs are pre-drilled to fit the Marine Band Deluxe, the Marine Band Crossover and the low-tuned Marine Band Thunderbirds. However, they can also be used to up upgrade a Classic Marine Band 1896 from the stock pear wood comb to a new custom comb. The conversion will require some hardware and some know-how. Below you will find links to a Marine Band Conversion Kit, offered on this website and a slide show providing detailed instructions about how to do the job. https://bluemoonharmonicas.com/collections/tools-and-kits/products/marine-band-screw-kit
