Standard Watercolor Boards - Feature a 100% rag, acid-free, 140 lb watercolor sheet mounted to triple-thick board. A very well known product, it eliminates the need for restretching. Please note: the board it is mounted to is not acid-free.
Premium Watercolor Boards - Feature the same high quality 140 lb paper but this time the paper is mounted to 100% acid-free, archival white core board. This is a lovely item and very professional. The paper is heavily sized so colors sit on the surface well and the sheet will take constant reworking.
A minimum purchase of 3 assorted boards is required.
