Hard Case

Where can i find a hard case heart shaped bag?
i have seen a couple of the hard case heart shaped bag on topshops website, i am looking for a basic version to customise myself, There is one on their website at the moment but it looks more of a night time bag for going out because of the union jack crystal design.
i am basically looking for a black hard case a bit like the infamous union jack bag but black.
If any one knows where i can get something similar plz answer it would be a great help
thanks
