Oops! This is the same design as my previous Chandani pin in shaded black, but with black metal instead of gold. This was a production error by the manufacturer but I didn't want them to go to waste, so I have a limited number available at a slightly discounted price. Once they're gone, they're gone! 
 
Soft enamel with butterfly clasp on the back. Laser engraved with studio name.
 
Approximately 4cm x 4cm/1.5in x 1.5in
