Nielsen Bainbridge 2200 board (formerly Letramax) offers a medium tooth designed for wet or dry media such as gouache, watercolor, charcoals, pencils and pastels.  Brad Buslik says its rag content provides the strength and even absorption needed for better control in wet media work.  The super-white surface enhances color intensity and fidelity.  The surface can also be stripped off the backing board for laser scanning or repositioning sections of art.  Available in single or double thicknesses.  Sold in carton quantities only.  Size 32 x 40 is oversized.  Extra shipping fees apply after checkout.
