Royal Brites22x28 Black Foam Board 4 Pack - Ideal Foam Board for Crafts - Lightweight Poster Sheets for School Projects, Presentations - Smooth Surface for Markers - Perfect for Home, Office Use

I use these for GOBOs in my studio photography. Great foam core boards that are affordable. Easy to work with, they also hold up well. I use heavy duty clamps to hold these in place during my shoots and have had very little deformation from the clamps. I highly recommend these.

This foam board is fine. It earns a 3 star rating because the corners were dinged in transit. They really need to look into corner protectors. The stickers came off easily without leaving any marks.
