Essentials Black Core - Double MatAdd to Wishlist
View Stock Mat Colors
Essentials Black Core matboard features a solid black core that along with the backing paper that touches your artwork is acid-free - buffered by an alkaline solution - and is recommended as design accent board for open-end reproductions, posters and decorative framing.
Opening Size Instructions
Openings are cut to the size you specify; normally you will want an opening 1/2" smaller per dimension than your artwork. This gives space to hinge and prevents it falling through the mat opening. So, for example, an 8x10 photo would use a 7 1/2 x 9 1/2 opening.
Sizes are listed by width first, and height second. Example 8" (width) by 10" (height).
Please make sure that the opening width and height do not exceed the size dimensions.
