15Pack Foam Core Board, 11”x15” Black Foam Board, 3/16” / 5MM Thick Mat Board Center, Foam Backing Boards for Mounting Photographs and Artwork, 3-D Modeling, Signage, Poster Making

They are smaller than they appear in the photos, and I ended up buying a second box. They perfectly black out the window in my second bedroom, which is also where I film my content, so if you are ballin on a budget and need to blackout a window, this is a pretty solid way to do so.

Decent foam core, black core and faces. Maybe a little more delicate than you find with typical foam core, but it looks nice and will work great on the project I bought it for. No issues cutting except the typical pilling/tearing/catching if you force the blade or whatnot.

The board is sturdy, arrived with good packaging to prevent bent corners. The black color is not Mat and has a bright reflection. Was used for photography, but the lighting needs to adjusted to prevent a reflected glare.

Adhesion is not applicable, since these didn't include adhesive. They are very foamcore! These are so foamcore, everything else is nocore. I used it for a foamcore craft project. Reliability is excellent. Durability is so far, so good. I haven't been keeping close track of time, I'd estimate about a few weeks of light use.

Use these for art projects to achieve a professional finish to my art
