An easy way to top off your Tumbler. Whether your day takes you to the beach or just the backyard, the Medium Press-In Straw Lid keeps your favorite drink ice cold and easy to sip. It features Honeycomb Insulation that helps keep cold drinks cold and hot drinks hot. The lid has an easy press-in fit for splash-proof dependability and a flexible straw that is durable and easy to clean. The lid is BPA-Free and Phthalate-Free, making it a safe choice. It pairs well with our 16 oz and 22 oz Tumblers, but is not compatible with the 16 oz True Pint. The lid is designed for everyday use and is suitable for both men and women.
