Where can i buy Pyramid studs/iPhone case?

I'm looking for some 'pyramid studs' (google them if not sure what they are) with FLAT backs so i can glue them onto an iPhone case, any ideas where i can get some relatively cheap? I've tried ebay, they only do the ones with spikes sticking out the back OR even where i can buy a black iPhone 4S case with studs already on it in the UK?

Search on google

Probably etsy.com

Try Tvc Mall
http://www.tvc-mall.com/

and ship everywhere.

Here is some links but those studs are flat they only looks like real so it can easy go into pocket, this is a UK site.
