Treat yourself to a delicious, delightful experience with MARS. These distractingly delicious, individually wrapped full size bars are great for sharing with coworkers and friends, gifting or enjoying all by yourself. There's no wrong way to enjoy MARS Bars. Always peanut-free, always delicious. Eating a MARS bar provides a true time out where all you can focus on is enjoying the thick chewy caramel and nougat, wrapped in a delicious chocolately coating.
