Seldex white mats (sometimes referred to as frame mounts) are top quality, 4 ply board that is 100% rag, acid and lignin free (black mats are acid free) with a bevel-cut opening and affixed to a back mount board. These mats are open at the top to allow prints to slip-in easily. Slip-in mats are available in your choice of white or black. An optional V-groove accent is available for an additional charge
