Former Apprentice winner Tom Pellereau has revealed his new business after teaming up with Lord Sugar on last year's show.
The 32-year-old "nice guy" has released his range of curved nail files, which will go on sale in stores across the UK on Sunday.
The S-shaped file was invented by Tom before last year's competition, with the Dyson-wannabe taking part in the show to secure Lord Sugar's £250,000 investment.
Tom's Stylfile collection is made up of the S-file, S-buffer and "emergency" S-file, will be priced at £4.49.
"Since the Apprentice final I've been working night and day to create the Stylfile Collection," Tom said. "Working with Lord Sugar and benefiting from his experience in retailing, manufacturing and marketing has been invaluable. It has been the experience of a lifetime, and seeing my product on shelf is a dream come true."
Lord Sugar added: "Tom has worked diligently this past year at developing the Stylfile and getting it to market. He's done extremely well at turning a very good concept into three excellent products and getting them stocked with some of the biggest retailers in the country.
"There's been a lot of interest from my followers on Twitter asking me what Tom is up to. Well, now they know."
A new series of The Apprentice kicks off on Wednesday on BBC One.
