Double your work space and increase the flexibility of your ThumBox with this hinged palette extension. Made of birch plywood and aluminum, it features holes to rest your brushes, and little metal feet that keep it elevated above your palette when closed. It easily attaches into the existing pilot holes on the ThumBox. It measures 6'' × 8''. Note: With the Palette Extension Kit installed, the ThumBox will only accommodate one wet panel.
