Kathfly6 Pack Large Foam Boards Bulk 3/16 inch Thickness Giant Foam Core Board Presentation Board Multipurpose Blank Board for Presentation Project Crafts Mounting School Display(30 x 40 Inch,White)

Bought these to mount my 2000 piece Buffalo Games jigsaw puzzles. They work perfectly.

These are super thin and cheap. They bow, dent easily, and will not withstand any pins, clips, or weight. You cannot pin them to the wall, the pins rip through. You cannot stand them up, they bow or are so light weight that they blow over.

Easy to use for doing jigsaw puzzles on dining room table. The 30x40 is sturdier that the standard 20x30 (which warps easily) and fits an entire 1000 piece puzzle with ease. I use 2 (see photo) one large sheet in the middle and one cut in half with the factory edges against the large one. The photo is just a 20x20 500 piece so plenty of room. Easy to move if need table.

These are brittle and arrive damaged. Even if they were not damaged these are far from quality. They snap with ease and are not real foam core. Equivalent to a fortune cookie type sturdiness. For real. Garbage.

I will use these for crafts and work I do on our community plays.

These boards are flimsy and not at all stable. When placed on an easel, the slides flop down like paper. The material is cheap -- more chemical than paper, if paper at all. It does not absorb marker when written on, so the marker stays wet and streaks or drips on the board. The corners are easily dented because the material is so weak. I would not at all ever recommend these boards to anyone for any purpose. You will be disappointed.

mixed feelings about this one. I wanted a lighter product, this was heavier foam that bends/wobbles. I was making a makeshift cubicle for a desk. It worked out with duck tape, but needed support all around. I made it work, but sad it cost me so much.

I didn't realize these would be so big when buying them. They are huge and make for fantastic art canvases, especially painting!
