Students will love this Mason Jar Tumbler with Mood Straw as an award for being a star student, honor roll student, or any other award. Why? The straw included with this 24 oz tumbler changes color in cold liquid! The clear tumbler features a mason jar style and twist-on lid, and comes with your choice of imprint printed on one side. Customize it with your school logo or a school event imprint, like Track and Field Day.
