These watercolor blocks contain sheets of premium, archival 100% cotton watercolor paper glued on two edges. As you paint directly on the top sheet in the block, the glue along the two long edges will hold the sheet flat. When your painting is dry, just slide a dull knife or letter opener in the open side under the top sheet. Release the glue along one edge and pull your painting free.
The 140 lb. blocks contain 15 sheets of paper, and the 300 lb. blocks contain 10 sheets of paper.
Fluid watercolor papers are sized with an animal-based sizing.
