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]

Where it's sold

A listing is evidence that this barcode is sold there, on that date; a price is what that listing showed, not a recommended price. Store links may be affiliate links (how this works).

Coverage measures the evidence recorded here. It does not rate the product.
