Designed to appeal to Britain's 3 million girls aged 5-15, the Fab lolly took its name from the Thunderbirds (1965-66) TV series'[not in citation given] catchphrase "F.A.B.", and from the numberplate of Thunderbirds' character Lady Penelope's pink Rolls Royce - FAB 1. Lady Penelope was used in advertising campaigns and Thunderbirds' gifts were given away with the lollies.
The lolly consists of strawberry fruit ice and vanilla ice cream with the top portion dipped in chocolate and coated with sugar confectionery. In the modern era, their popularity has dropped and been replaced by lollies such as the Twister and various ice snacks based around cartoon characters, however Nestlé still continue production of the iced snack into the 21st century, both as a single item and as part of a multipack.
The description on the packaging reads "Real Strawberry and vanilla flavour ice lolly with chocolate flavour coating (5%) and sugar strands (5%)".
The fab lolly, Fruit And Berries, has changed from a jelly type centre many years ago, to strawberry ice used now. An Orange variety has also been manufactured as has a limited edition lemon flavour  and a limited edition apple and blackcurrant flavour (in 2010).
