What should i get my sister for her 24th birthday?

So its my sisters 24th in two weeks time, and i want to get her something really special, or just lots of little fun, useful presents, but i just don't know what, i have a budget of �30 since she just passed uni and has got a job in one of the biggest companies in her area, so this present is also part congratulations:) (my sister is really fashionable, always loses her phones and cameras or breaking them when she goes out clubbing) any ideas?
