About this product
Mars 2 Pack King Size is the twin-bar king-size edition of the Mars bar, the caramel and nougat bar in milk chocolate that Mars, Incorporated has made since Forrest Mars Sr. first produced it in Slough in 1932.[1] The only photograph of this barcode shows the black Mars livery with "2PACK" beside the logo and a corner flash reading "2PACK KING SIZE".[2] Open Food Facts holds the code as "Mars 2 Pack" with a Dutch-language front and neither an ingredient list nor a panel,[3] and the 2006-2013 Barcodepedia recorded it in November 2008 as "Mars", described only as a "2er Pack".[4]
More about this product
Wikipedia's account of the bar's sizes has the 84 g king-size bar of 2008 replaced by an 85 g pack of two bars, sold as Mars Duo,[1] which is the format this wrapper advertises; no source found gives this article its own weight, market or label, so those cells stay empty. The barcode sits under GS1 UK prefix 5000159, whose registrant no public source names; Mars Wrigley Confectionery UK Limited of Slough, the group's British confectionery company, is recorded as the derived prefix owner.[5] The composition shown is the one published for the current two-bar Mars pack and is declared secondary, not this pack's label.[6]

Coverage measures the evidence recorded here. It does not rate the product.
- Identity: 3 / 3 · Name, brand and classification recorded
- Context: 2 / 3 · Evidence groups assigned to a researched label, edition or analysis
- Label photographs: 0 / 2 · Researched contexts with an assigned photograph
- Published composition of the Mars two-bar pack 5000159408301: nutrient evidence: 8 / 8 · Recorded nutrient rows linked to a source; not the number of nutrients that ought to exist
- identity · unknown: Net content is not established: no listing ties this GTIN to a weight. Wikipedia records an 84 g king-size Mars bar replaced by an 85 g two-bar pack, which is not evidence for this article.
- ingredients · unknown: No ingredient list for this pack has been read; the Open Food Facts record carries no ingredients text and only a 296 x 79 px front crop.
- nutrition · unknown: The pack's own nutrition panel has not been read; the values here are the composition published for the sibling twin pack and are declared secondary.
- markets · unknown: No retailer listing was found for this GTIN. Open Food Facts tags the record Belgium and its front photo is the Dutch-language front, neither of which is market evidence, so country_of_sale is left empty.
- relationships · unknown: Nothing found names the manufacturer, packer or the registrant of GS1 prefix 5000159; the 2008 Barcodepedia page's "produced in United Kingdom by Masterfoods" line was generated from the prefix.
- evidence · stale: Evidence was observed over a year ago; check for newer labels. Historical evidence remains valid.
- schema · schema_gap: Review and assign legacy facts to coherent observations.
