The candy known for its tagline "Melts in your mouth, not in your hands" is M&M's. Introduced in 1941, M&M's are small, colorful candy-coated chocolate pieces. The slogan emphasizes the candy's unique features, promoting its ability to stay intact and prevent messiness. Each piece has a hard candy shell, which helps keep the chocolate inside from melting too easily—hence the catchy tagline. M&M's have evolved over the years to include various flavors and types, becoming a popular treat in cinemas and homes alike. The brand's appeal extends to promotions and advertising campaigns, helping it maintain a prominent place in pop culture.
