Mentos is a popular brand of mints sold in many markets across the world by the Perfetti Van Melle Corporation. Mentos was first produced in the Netherlands during the 1950s. The mints are small oblate spheroids, with a slightly hard exterior and a soft, chewy interior. They are sold in rolls which typically contain 14 candies, although the new "Sour Mix" flavor contains only 11. Certain flavors are sold in boxes in the United States and the United Kingdom, and the rolls in three and six-packs. The slogan of Mentos is "the freshmaker". Most Mentos packages describe the candy as "chewy dragées". The typical Mentos roll is approximately 3/4-inch in diameter, 6/16-inches tall and 1.3 ounces.

The singular for Mentos is "Mentos". (The popular slogan reads, "Mentos—the freshmaker" as opposed to "Mentos—the freshmakers".) Furthermore, the Mentos television advertisements state, "Mentos, it freshens."
