i have to see that charm. but my whole point was using the awesome carmencita...Hermes do a phone charm - I have one - a tiny enamelled disc in the tohubohu design - so small you just get a couple of the letters and numbers.
However, I love the idea of a carmencita too, it looks great in the pic. The accessories are better value if they can multi-task! (Trying to justify the costs!)
