I looked all over for panels this size and am very impressed by the quality of these. Very easy to hang up too.

This bulletin board is slim and low profile but seems to stay in place well. I was able to secure this one using two sticky tabs to each panel. The panels are mostly square but off enough that by the end you may have a few gaps. It comes with all the installation materials and 2 boxes of factory grade push pins.

These are so fun! My 10yr old daughter hung her own and she is thrilled. They are decently sturdy, have an interesting bevel detail around the edge. They install using sticky pads. I’m a little worried about what it will do to my wall, but we’re giving it a shot.

This is a nice felt bulletin board. I like it that they have the 12x12 squares and you can make them in any shape you like. It’s a bonus that it includes push pins. The stickers to hang are clear and thin but very difficult to remove the backing. I found that warming up the edges before peeling helped the backing come off a little easier. If you are looking for sound dampening it does very little on that part. I think more squares need to be used for that to work best.

These felt tiles are perfect for a thin bulletin board. But they are a little thinner than I expected, so they definitely won't serve as noise protection or sound dampening in an office setting but that's not the intended purpose.
