I've used Command hooks for years but I think the clear ones may be a problem. I used these to hang light picture frames on the wall. In the beginning they were great. Instructions to hang were followed. Now, about 6 months later, I've had several frames fall off the wall because the hook no longer stuck. I guess these are good if you just want to hang things for a day, but to avoid damaging precious items and having to clean up broken glass, I suggest using something else.
