I was super skeptical when I first opened these hooks but couldn’t believe how PERFECT they are for my mantle and probably for ANY fireplace mantle for that matter! You can adjust them to size for whatever width you need to get them to securely fit over your mantle edge and it couldn’t be easier. They are plain enough as well (in the best meaning possible) to fit with any decor! Love, love, love these! I’m so happy I planned ahead and bought 12 more than I currently need for when additional grandchildren arrive.
