The launch of the new product looks to be set for September this year – 2010.
Mars is hoping to profit from increasing consumer demand for lower calorie products with the introduction of the Twix Fino.
Twix Fino has a wafer base rather than a biscuit base and each finger contains less than 100 calories, compared to the normal Twix biscuit fingers which contain 130 calories per finger.
The product is looking to be marketed towards the female, health conscious market, competing with other brands lower calorie chocolate products, such as KitKat Senses.
A twin-pack Twix Fino will retail at 52p.
