This 20oz stainless steel tumbler, designed by Dunbi, is perfect for keeping your drinks at the ideal temperature while you're on the move. The included straw adds extra convenience. Made from 100% stainless steel, it's durable and resistant to rust, staining, and corrosion. Measuring 9*7*17CM, it has a plastic lid to prevent spills.

Using this tumbler is easy. Just open the plastic lid, fill it with your favorite drink, and put the lid back on. The straw makes sipping your drink hassle - free. When it comes to cleaning, you can use warm soapy water and a soft sponge to wipe the inside and outside. Avoid using abrasive cleaners as they may scratch the surface. To keep it in top condition, dry it thoroughly after cleaning. Don't leave it in direct sunlight for long periods as it might fade the colors. Also, make sure to tighten the lid properly to prevent any leaks.
