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 Snacksize is a multipack of nine 33.8 g Mars bars, 304.2 g in all, sold in the United Kingdom and Ireland; each bar is milk chocolate with a soft nougat (32%) and caramel centre (27%).[1] Mars is the caramel and nougat bar Forrest Mars Sr. first made in Slough in 1932, and Mars Inc. produces it.[2] The wrapper photographed in December 2019 gives a British freephone and Freepost address for Mars Wrigley Confectionery UK Ltd. beside an Irish contact for Mars Ireland in Dublin, carries the Fairtrade Cocoa Program mark and is marked suitable for vegetarians.[1] UK discount grocers still listed the pack under this barcode in 2026.[3][4]

Snack-size bars sit between the full bar and the Fun Size miniatures in the Mars range; as of 2008 the miniature sold in multipacks, Snack Time, weighed 36.5 g.[2] UK retailers now also list an eight-bar Snacksize pack of the same 33.8 g bars, 270.4 g in all.[5]

Where it's sold

Coverage & research gaps (9)

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

  • Identity: 3 / 3 · Name, brand and classification recorded
  • Context: 1 / 2 · Evidence groups assigned to a researched label, edition or analysis
  • Label photographs: 0 / 1 · Researched contexts with an assigned photograph
  • English GB and Ireland label on the 9 x 33.8 g multipack wrapper: nutrient evidence: 16 / 16 · Recorded nutrient rows linked to a source; not the number of nutrients that ought to exist
  • markets · unknown: amazon.co.uk searched on 2026-09-25 for "Mars snack size 9 x 33.8g", "mars" and 5000159521406 (the store search answered with a bot challenge, so the searches ran as site:amazon.co.uk web searches and /dp/ fetches): no listing of this 9-bar pack. B08D8X6KFR, whose URL slug reads Mars Chocolate Snack Multipack 33.8g, is now titled "Mars 8pk" at 270.4 g and GBP 2.99, and B085BLSHVV is "Mars 8 Snacksize Bars, 270.4 g": both are the 8-bar article.
  • markets · unknown: amazon.ie searched on 2026-09-25 with site:amazon.ie web searches for "Mars snack size bars multipack 33.8g" and the brand, and /dp/B08D8X6KFR and /dp/B085BLSHVV on amazon.ie (both 404): no listing of this pack; only protein bars and mixed fun-size bags.
  • identity · unknown: UK grocers (Tesco product 321214695, Morrisons 504496011, Amazon B085BLSHVV) now list an 8 x 33.8 g (270.4 g) Mars Snacksize multipack. Whether it replaced this 9-bar pack, and on what date, is not stated by Mars in any source read, so status is left unset.
  • nutrition · stale: The panel and ingredient statement were photographed on 2019-12-07; no newer photograph of this barcode is on Open Food Facts as of 2026-09-25.
  • images · unknown: The front photograph shows the pack on a shop shelf, partly behind the shelf-ready tray; a flat front scan would read the full front.
  • 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.
  • ingredients · not_researched: Ingredient statement or sourced exemption not recorded.
  • nutrition · not_researched: Nutrition declaration or exemption not recorded.
