Laminated enameled aluminum easel with holds panels in an elevated position and stores neatly in the 9 by 12 Guerrilla Box lid. Allows the use of more gestural brush strokes on 12 by 16 or smaller panels because your painting is held out away from the lid. Adjustable metal fingers adjust to hold panels up to 12-inch high by any width. You can also paint smaller (4 by 6) if you turn the panel "upside down" so that the aluminum shelf on the Slip-In Easel is at the top. For best results, use with Panel Adapter Clips (included with the 9 by 12 Guerrilla Box). (NOTE: The Slip-In Easel limits the carrying capacity of the Guerrilla Box to two wet panels.) Enameled aluminum laminate with aluminum hardware.
