In the BBC series Dragon's Den, entrepreneur Tom Pellereau invented the nail-care product range Stylfile.
Pellereau presented his curved nail-file idea to the Dragons and secured investment from Lord Sugar. The distinctive shape was designed to follow the curve of a fingernail, making filing easier and helping users reach areas that are awkward to shape with a straight file.
The appearance is notable because Pellereau became associated with a product developed from a relatively simple everyday problem. Stylfile later expanded beyond its original filing concept into other manicure and nail-care products.
A common mix-up pairs Pellereau with Shaun Pulfrey, another entrepreneur whose grooming product appeared on Dragon's Den. Pulfrey created Tangle Teezer, the hair-detangling brush, while Pellereau created Stylfile.
