Review on 📦 Mat Board Center - Acid-Free 11 x 14 Inch Black Foam Core Foam Boards - Pack of 10 Sheets by Carol Miller

I used them to make a modern back cover for my TV. It hides the ugly wall mount and houses in the wall and gives the dark background needed to really make my 4K HDR image stand out. I used hot glue to attach them which showed up in a few places but I could easily have used a stronger glue and didn't have this problem. I keep a box of these handy for other small items, I've even used them to cover the back of my desk to hide the cables and printer. Double-sided tape works well for this use. They are well made, thick and evenly cut. They're versatile and the cost is solid.
