Review on 🖼️ 10-Pack Adhesive Picture Hangers - Plastic Sawtooth Hooks for Easy Hanging - Ideal for Foamboard by Kanwar Mix

I had these old hangers a few years ago and they worked great. They are useless and dangerous to use if you care about what you hang. I used them to hang posters on foam board and the several ounce weight of the poster ripped them. At first I thought it might be a defective hook. But now it happened 8 out of 10. When the posters fell, at least one corner was crushed, ruining the poster. I hope they can be reinstalled but I'm not sure if they can be removed from the foam board to install on another element. THAT IS TRASH! I wish there was a way to give 0 stars. UPDATE: Two more posters fell down, so 10 out of 10. The glue wasn't a problem. The piece of plastic actually breaks under the weight of a poster.
