No more taping or mounting pastel paper - these mounted boards are designed for easy use, storage and transport. Pastel Premier Conservation Board features quality sanded pastel paper that is mounted on a 4 ply conservation board, double-primed and coated with an aluminum oxide to produce an idea surface for pastel painting. The base paper is heavy, which withstands any measure of scrubbing and re-working. This versatile board accepts as many as 25 layers of pastel! It works well with oil and acrylic paints as well as colored pencils and other dry media.Details:Available in multiple colors and sizes2 panels145lb /300 gsm100% cottonArchival qualityAcid free and neutral pH
