The introduction of Galaxy Bubbles this month will be supported by a £2.5m launch spend.
Galaxy Bubbles has the same Galaxy taste in the form of its chocolate shell, and is filled with an aerated Galaxy chocolate centre.
It will be available for sale in single bar format (rrp 52p) as well as multipacks of four (rrp £1.69).
The product is expected to have strong impact in store through the use of point of sale, which is available nationwide and includes dumpbins and counter units, according to Bep Sandhu, trade relations manager at Mars Chocolate.
"The launch comes off the back of a very successful year for Galaxy and we are confident the product will be well received by the trade and our consumers," she says.
