Excellent Way to Display Art for Sale. The iFrame Pack comes in a cardboard box with the pieces carefully stacked. The mats are pristine. The backing is stiff and the plastic sleeves are very clear. The 11 x 14’s are not bottom weighted but sit centered cutting 1/4″ off the edges of an 8 x 10 picture. These mats are just what I need to sell my photos without breaking the bank.
