I bought these about a year ago thereabouts - as I was taking them down to move I realized I never left an actual review. Frankly, they've been amazing. They were easy to apply and held the weight of my pins with ease (and a good number of them are metal, including the ones that I've added since this original photo, so I would consider that an impressive feat). Upon removal of the pins, the felt does retain some pin pricks but otherwise no damage to the fabric. I took the boards down today and it was frankly the easiest adhesive removal I've ever had short of command strips. They came off easily, only left a bit of residue, and from what I can tell did no damage to the wall (any flaking in the second image is actually from the adhesive backing). It'll just take a bit of a wipe down with a cleaner to remove it entirely. The backing is still pretty sticky, but I would definitely recommend getting more adhesive if you're planning on reapplying them (unfortunately this company does not appear to sell their adhesive sheets in bulk from what I can tell. Seems like a lost business opportunity, but oh well).

Only caveat I would give is that the tacks the board are poor quality and clunky haha. If you were buying these just for the tacks I would recommend saving yourself the fuss and getting them from a dollar store. But assuming you're here for the boards themselves, they're pretty good.

For some reason the tan pin tiles never stayed on the wall they always fell off. But every other color held on.

Have been using these for my wall as both art and a bulletain board. Installation is easy, and even if you are a little slanted, as long as you don't smear the whole thing on the wall, you still have a few seconds to peel it off without causing 'dramatic' damage to your wall. Granted some paint will probably come off if you do it continuously or if left on for too long, but still, its more than adequate for re-positioning. They also fit together very snugly and neatly making it easy to put in a satisfying formation.
Whether you need a bulletain board or just want something to spruce up your wall these panels work great for both! Though if you are covering a large portion of wall, I'd buy either more than one packet or get a larger quanitity package of these panels, depending on the formation you want to make with them the space they encompass with only 6 panels is a bit small (around a 14 inch by 12 inch patch or a long line of singles spanning around 28 inches). 10/10 would highly recommend.

Eye catching. Makes a bold statement. Love the colors.

Super cute, I took off one star because the shape of each one isn't consistent (corners and lines don't match up like they should), and because the adhesive isn't the best. We have plaster walls though, so it may stick better to drywall. Nothing has fallen, but I also don't keep anything with much weight pinned on it. That said, you'll see I have only 3 tiny Polaroids on the bottom white hexagon, and that one is starting to separate from the wall a bit.
