I ended up, not needing to keep these curtain rod holders because the rods that I ended up purchasing had all of the hardware which I didn't know they would. You get a lot of of these rod holders and I got them because they were inexpensive. But I didn't realize that they aren't open on the top where you would place the rod into. The picture looked like to me that they were open and you would click them close shut so for that reason I didn't give many stars. I also am not sure about the size curtain rod that would be able to be used with these rod holders. They did seem a bit cheap as far as if I needed to screw them to the wall the plastic wood, crack, and or break. While you have the choice of using the self adhesive alone, I would say that any decent curtains you are wanting to hang. You will also need to have them attached with the screws that come with it. Maybe if the curtains you are hanging are sheer and don't weigh anything using the self adhesive option would work fine.
