• Color Match: The deep blue / midnight blue shade reproduces consistently and frames a wide range of images without overwhelming them.
• Custom Options: Custom opening sizes are available on request, so buyers who need a different reveal can order a tailored cut.

Who It's For

This mat is ideal for hobbyists, photographers, gallery preparators, and small frame shops that want a reliable, standard mat for a 17x26 image and a 21x30 frame. The combination of 4 ply material and archival content makes it appropriate for keepsakes and portfolio pieces that should remain stable over time.

Those who should look elsewhere are buyers who need decorative beveled edges, unusual thicknesses, or a fully bespoke framing service; this listing supplies the mat only and does not include ornate treatments or the frame itself.
