A traditional butcher tray palette can be used with any paint mediums. Great for most watercolor color mixing as color can be used even years after it has dried out on the tray making them highly functional. Due to manufacturing process many trays have small chips in the upper rim area and the color of the enamel varies from batch to batch from bright white to creamy white giving them a distinct old world feel. Designed so that the bottom is slightly bowed so that the tray is higher in the middle than around the edge helps control water to pigment ratio. This is a tool that will last a lifetime. 7 x 10.5"
