Which Dragons' Den entrepreneur invented the Stylfile curved nail-file range?

Tom Pellereau invented the Stylfile curved nail-file range.

Pellereau is a British inventor and entrepreneur who won investment on Dragons' Den for Stylfile, a range of ergonomically shaped nail-care products. The design used a curved form intended to make filing around the shape of a fingernail easier than with a conventional straight file.

His pitch became notable because the product was simple, clearly demonstrable and protected by design and intellectual-property considerations. The business later developed additional nail-care products and secured retail distribution.

Stylfile is sometimes confused with ordinary curved nail files sold under unrelated brands. The distinctive point is that Pellereau created the product range and presented it to the Dragons; he was not merely a retailer or distributor. His story is often cited as an example of a small physical invention becoming a commercial product through televised investment.
