Mat Board Center, 10 Pack 16x20 Black Uncut Mat Boards/Backing Matt Boards for Crafts, Frames, Photos and More

The thickness is fine. I use them to mount photos that are displayed on a wall by our camera club.

I’ve never purchased Mat Board before, so I don’t know what to look for. The core is White, the outsides are black and it seems to cut well with an exacto knife, only getting caught on the black paper a few times. I think it would’ve worked better if I had an actual Mat cutter. Happy with the result and that I can make then whatever size I want.

These are great and so easy to use

Some of them did have bent corners as others have noted so definitely make sure you're getting a size bigger than you need. I cut the edges off mine so it wasn't a big deal. It was my first time trying to frame anything so I can't tell if these are good or bad but they looked good and I liked the colour choices.

Perfect was the perfect size loved all the different color options came in a great package. No papers were bent. Very durable. Great value for my money. I’ll be able to use all the other pieces.

I originally got this mat board for my frames, but I also realized it worked perfectly for photographing my ID—you know how tricky those can be. It fit exactly in the frame with no shifting around, and the black was nice and even. Plus, it came well-wrapped, so no scratches or friction marks. The thickness was perfect because some frames could be really unforgiving. Super handy excellent value.

This mixed color box of uncut mats is perfect for the project I’m in the middle of. Happy with them!

Good thickness. Corners were very slightly bent, but that part is covered by the picture frame anyway so it doesn't matter. But something to note if you aren't planning to use these with a frame I guess.
