MBC Mat Board Center, Pack of 5, 8x10 for 4x6 White Photo Picture Mats - Acid Free, 4-ply Thickness, White Core - for Pictures, Photos, Framing

They were 8x10 mats but the opening was for a 5x7 picture, not a 4x6.I'm disappointed!! I will keep them, I might use them eventually, but I'll go buy what I need. don't have time to wait for a replacement!

Was waiting for these in order to mat some small pieces of art. Unfortunately both dimensions of the mat opening were larger by a whole inch each way, than what was stated in item description.

These don’t fit 4x6 only 5x7
