What the sources say about these ties
- Mars, Incorporated owns
- Wikipedia names Mars Inc. as the producer of the Mars bar since 1932.
Built from the ownership rows on the brand and company pages, each cited where it is recorded. Made in is the country of production on this product's record; the GS1 prefix of a barcode names the issuing organisation, not where the product was made.
About this product
Mars Duo 78.8 g is the two-bar pack of the Mars caramel and nougat bar in milk chocolate, two 39.4 g bars in one wrapper, and the successor to the king-size single Mars bar.[2][3] It is made in the United Kingdom by Mars Wrigley Confectionery UK, whose earlier name Mars Chocolate UK Ltd, Slough, is printed on the wrapper beside an importer line for Mars Chocolat France at Haguenau, so the same pack served British and French shelves.[4][1] The bar is described as milk chocolate with soft nougat (32%) and a caramel centre (27%), at 448 kcal per 100 g and 177 kcal per bar.[4][3] It is labelled suitable for vegetarians and kosher under the London Beth Din.[4]
A British wholesaler added this barcode in January 2014 in cases of 32 at a recommended price of GBP 1.50, and a London convenience store still sold it at GBP 1.45 in September 2026.[4][5] When Wikipedia described the range as of 2008, the Duo weighed 85 g.[2]

- ingredients · disputed: The Dee Bee data sheet lists whey permeate, palm fat before lactose and vanilla extract with no hydrolysed milk protein; the Open Food Facts and USDA text lists whey powder, hydrolysed milk protein and natural vanilla extract. Which is the later label is not dated by either source.
- identity · unknown: Dee Bee marks this EAN No Longer Available and the family page records 5000159551724 as the UK Duo and 5000159519328 as the French one, but no Mars page states that this code was withdrawn; status is left unset.
- markets · not_researched: Amazon.fr: web searches for Mars Duo 78,8 g found only lots of 3 (B013P4YIVO, EUR 4.59 on 2026-09-25) and 6 (B013P4YLBG) bars, not the single pack, and no page printing this barcode; the store's own search answered with a bot challenge.
