Calling all photographers, artists, and crafters! These acid-free mat boards are exactly what you need to make your artwork and photos look professionally framed. This pack comes with 5 white mats that measure 11x14 inches and are pre-cut with two openings for 5x7 inch pictures. The opening sizes are 4.5 by 6.5 inches, giving your photos that perfect border that makes them pop. What's really important is that they're acid-free with white core - this means they'll protect your precious photos and artwork from yellowing and deterioration over time. The 4-ply thickness (about 1/16 inch or 1.4mm) gives them that substantial, professional feel without being too bulky. The bevel cut edges add that nice angled detail that catches the light beautifully. Whether you're framing family photos, art prints, certificates, or any other precious paper goods, these mats provide that extra layer of protection while making everything look more polished and gallery-quality. They work with standard 11x14 frames, making the whole framing process super simple. With 5 in the pack, you can frame multiple pieces at once or have extras for future projects. Seriously, if you want to take your framing game to the next level without spending a fortune at custom framing shops, these mats are the way to go!
