I've put some objects ranging from coffee to hand made jewellery, phone and used camera but still nothing sell
Probably the market in Italy/Europe is still too little for this service
You must also look what people are using bitcoin right now, probably 90%+ male and geeky type of people.
They probably have smartphones already and don't want jewellery type stuff.
For example a few weeks ago someone was selling raspberry pi, they all have been sold in rather short time.
But sometimes it just takes a little longer, I had a usb wlan stick that took months until someone bought it
