Modern paper mills use small-structure cellulose to make paper. The original paper mills used fiber instead. For tipping paper to perform best it needs to be made from fiber ndash; not just boiled cellulose. Fiber-based tips roll smooth AND have enough structural rigidity to both keep its shape in your mouth AND to not dissolve. There are precious few of the original Fourdrinier paper machines in use because they're antiques and expensive to operate. RAW was lucky to find this old mill it's the only one in the world that can produce RAW tips to top class specifications.
