MBC MAT BOARD CENTER Foam Core Backing Boards ( Black , 11x14 3/16, 10)

Perfect for what I expected

It is very sturdy but the paper was peeling off so I glued it back!

I use these for light control in photography projects. Their very sturdy, easy to cut and hold together easily with masking tape.

I liked these but did not actually use them for the project intended they are thick have a core

Just perfect for my project of creating dividers my dvd collection.
