Polish designer Michal Jonca has come up with an effective way to attract attention. He has created a line of jewellery that resemble the micro-chipped security devices that you often see attached to clothing in retail stores. Made from poured resin, the pins come in three different designs and are available in a range of colours. The device designed to prevent shoplifting has now become a fashion statement. Wear it on your jacket, hat or shoe and pretend you didn’t know it was there.
