Transportation and storage boxes, perfect for 2-D artwork. I used them for several years to transport and protect my photography, however I have now retired from doing art shows and no longer need them. Each box is made from heavy corrugated plastic; has a foam insert in the bottom; and a metal frame around the top to which the lifting straps are attached. There are 7 boxes total and all are in good condition. Interior dimensions are: 25x37x7, 42x32x4, 45x36x4, 40x18x8, 25x20x8, and two at 23x20x8. Cost when purchased new was between $75 and $125 each depending on size. Asking $250 for all 7 boxes.
