Mount, screws etc. for roller blind (NW11)

Someone picked up a roller blind from me earlier this week but I don't know who, because I gave my address to several people but nobody bothered to confirm whether it was they who picked it up.

If you are the person in question, you probably want these pieces as they are needed to affix the blind to a wall surface. Otherwise you just have a blind that you will need to hold by hand, which will be rather inconvenient if you want to go anywhere away from your window.
