Portfolio Boxes will hold a maximum of 10 mats (shallow size), 18 mats (standard size), or 25 mats (deep size). Mats sold separately.

For Folio Boxes, the capacity is 10, 15 or 25 mats. Mats are included with the box.

Seldex mats are top quality, 100% pulp mats that are acid free and alkaline buffered to combat the natural aging of the paper, protect your print, and ensure longevity. All openings are bevel-cut, and each top mat is 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

If you are using Fine Art paper or a thicker stock than standard lab prints please be sure to select "unassembled" so your Frame Mount and base arrive separate for you to assemble.
