Our Standard Mats by Crescent® are high quality, 4 ply (1/16") mats, available in a large range of colors. They are buffered to a neutral pH (acid-free) that provide a 7-12 year life span for protecting artwork -- suitable for most everyday matting needs.
!! Custom Openings, if selected, will be cut EXACTLY as typed in. Make sure dimensions are smaller than the paper, so the photo/artwork does not fall through the opening.
Example, if photo is 8x10, you may want to type in '7.5x9.5'. That will give you a .25" overlap on all four sides.
