Ready to keep your water, smoothies and cold brews ice cold for 24 hours, the Takeya 40oz Insulated Straw tumbler is crafted with double-wall insulated stainless steel and sweatproof powder coating. Easily grip and twist off the ambidextrous lid and fill your tumbler with your drink of choice and ice through the wide mouth opening. The splash-proof gasket keeps every drop inside when you put in your straw. The cupholder friendly base fits in most cars and includes a protective bumper that you can remove when needed. Each tumbler comes with two Titan™ straws in standard or jumbo size. When you’re finished for the day, the lid and cup are dishwasher safe, making it easy to clean.
