Pretzel M&M's 40 ounce bag from Mars. For some, a large dose of Pretzel M&M's is needed because a single bag won't do. If that describes you, then the 40 ounce bag of Pretzel M&M's has your name on it (well, not literally). The classic M&M flavor and delicate crunch is enhanced by a second crunch with a hint of salt. Pretzel M&M's 40 ounce bag is re-sealable. Order a few today.
