RayMar's Wet Painting Carriers protect your wet or dry paintings when painting plein air or traveling home from a workshop. These fluted polypropylene plastic carriers are waterproof, lightweight and strong. Each carrier will transport up to six 1/8" panels. For the best protection, we recommend the artist puts one freshly painted wet painting in each of the three slots. If the paintings are dry to the touch, they can be placed back to back, two in each slot. With a velcro closing lid and adjustable carrying strap, the RayMar Wet Painting Carrier is convenient for any paint out, workshop, or trip.
