These black acid free mats have a white reveal. They fit in an 11x14 inch frame and display an 8x10 inch photograph. I am also including ten resealable plastic sleeves to protect your unframed matted artwork. These are sized to fit an 11x14 inch photograph or 11x14 inch mat with photograph and backer board. The adhesive strip is on the back of the envelope so that it will not come in contact with your artwork. They are perfect for displaying at art shows, to present as a gift, or for long term storage. These items are all unused. Photograph in last image not included. I have twenty of these mats altogether and am willing to create a new listing if you require a specific amount.
