This palette has 18 easy-to-clean paint wells; each with a width of 1-7/8 inch and plenty of mixing space in the center. Made with the same rugged plastic as the original John Pike palette; with outer dimensions being 10-1/2 x 15 inches. Comes with a sturdy lid that snaps closed to keep your paints clean.
