MBC MAT BOARD CENTER 12x16 Black Uncut Mat Boards (25)

These MBC MAT BOARD CENTER 12x16 uncut black mat boards (25 pack) are acid-free, 4-ply backing boards with a white core designed for framing, photo preservation, and DIY crafts.

Whether you mount prints, back framed photos, or craft event signage, these 12 x 16 black uncut mat boards give a sturdy, archival-ready backing that you can trim to size. Each pack contains 25 boards with a crisp black surface on both sides and a white inner core; the 4-ply construction provides resistance to warping while remaining easy to cut with hobby tools. They pair well with mats, clear sleeves, and standard 12x16 frames to create clean, professional displays or one-off personalized projects.

How do these mat boards protect photographs and prints?

The boards are manufactured without acidic additives, so they reduce long-term discoloration risk for photos and paper-based art. Their 4-ply thickness adds a protective layer that keeps items flat and supported inside frames or portfolios.

• Acid-free composition preserves photo edges and paper fibers.
• 4-ply thickness (~1/16") resists bending and provides rigidity.
• Black surfaces on both sides hide seams and backing materials.
• White core offers a clean, finished edge when cut or beveled.

Can I trim these boards to custom sizes and shapes?

Yes — the uncut format is intended for customization. Use a straight edge and a craft knife, or a mat cutter, to produce precise borders and shaped openings for portraits, prints, or handmade signs.

• Score and snap for straight cuts; use a mat cutter for beveled windows.
• Clean white core shows a neat contrast after trimming.
• Works well for layered mat arrangements and multi-window projects.
• Suitable for event décor like signage, table displays, and invitations.

How do these backing boards perform in framing workflows?

They are sized for 12 x 16 frames and slide easily into common frame sizes as backing or spacer boards. Their durability simplifies handling during matting and framing, reducing the chance of creases or damage while assembling pieces.

• Standard 12x16 dimension fits many ready-made frames and archival sleeves.
• Double-sided black finish gives a uniform look if visible from the back.
• Sturdy core supports heavier prints without sagging over time.
• Pack of 25 keeps you supplied for series projects or retail framing jobs.

What crafting and display projects are these best for?

These boards are versatile: use them for framing photos, mounting artwork, tabletop signage, wedding and party decorations, school projects, and portfolio backing. Because they’re easy to cut and stable, they’re a preferred choice for hobbyists and small studios.

• Create custom picture mats, layered displays, or photo mounts.
• Cut into shapes for party décor, place cards, or gallery labels.
• Use as a rigid backing in clear sleeve presentations or print packaging.
• Ideal for classroom, craft fairs, and small business product displays.
