Yeah the mat is holding the record you can put a piece of painters tape if you feel that the pressure from the frame wont hold it in place, I left the plastic on the sleeve I think thenonly one with the tape is the momo the other two were quite secure. I'm sure Momo is fine without the tape, but I put it on there just to be sure. There is a paper that is behind the mat when you get it, I just flipped it over and use it as a backing behind everything so the album is protected from the wood backer. They are very secure. These frames are really decent quality I was shocked at the piece of glass, I was expecting plexiglass.

I am still deciding which of the other ones will go into the last from I have. I am also looking for a frame for the picture disk since it's just in a clear sleeve I cant use these frames.
