Plein air panels are made from quality 1/4 inch birch plywood.  Birch plywood is well known for its usefulness in creating painting panels.  The high quality look to the back of the panel will impress your patrons.  They are suitable for both plein air and studio painting.
 
The panels are pre-sealed with a non-toxic water based sealer to reduce the effects of moisture in the environment and mediums used on the panel.   These panels are prepared with high quality acrylic primed canvas.
