Canson MiTientes Boards - 16 x 20 Inch Board - Pack of Five Boards - One of our most popular pastel papers is now available mounted on a 16" x 20" white, acid free conservation mat board. Artists familiar with Canson MiTientes papers know that both sides of the paper are usuable, one side is rougher than the other. This board features the rougher side. We have sixteen colors on the way. We hope to be able to ship by the first week of September. Due to packaging concerns, we require a 5 sheet minimum order.
