When paper manufacturers in England needed to make a thicker board, they would ship their paper "plys" to Bristol to be joined together to make what is now known as Bristol Board. Generally 23x29, Bristol board come in various thicknesses or ply ratings and in smooth plate finish or a slightly rougher vellum finish. More expensive Strathmore 500 Series Bristol Board is made from 100% Cotton Rag for maximum whiteness, archival quality and best performance. Paris Paper For Pens performs like the more expensive rag boards but at a lower price.
