They look nice but they aren’t sturdy and do not hold much weight. I’ve bought better ones on Amazon.

Really good wall amounts. I used the drywall anchors and it feels sturdy. I put like a 3 pound Crystal on it and it’s holding perfectly fine. I also was able to paint them with no problem would buy again.
