My stamps I ordered have arrived this morning. They are A6 size and cost £1.99 including post. Each stamped first time (Colorbox ink), but I had to take a scalpel to the musical notes because there were a couple of 'blobs' in between the lines of notes. Just skimmed them off the surface and it stamps fine.
Add on: Forgot to say I really only wanted them for the musical score but it was a set. There are also a couple of lovebirds that I forgot to photograph.
