Perfect for anyone who doesn't want to give up their coffee or tea on the go: the Leifheit Flip insulated mug, 350 ml in red. It is 100% leak-proof and therefore completely spill-proof. Additionally, it can be easily opened with one hand without needing to set it down. The push-button for opening the lid can be conveniently operated with the index finger. An additional lock on the lid prevents accidental opening, allowing the mug to be carried in a bag without worry. The lid is also equipped with a soft-grip surface for better handling and easy twisting. With its foldable handle, the Flip insulated mug can not only be carried comfortably but also offers the option to attach it to a backpack or bag. A removable filter allows for the addition of herbs without interfering with drinking. Thanks to the double-wall insulation made of stainless steel, beverages in the Flip insulated mug stay hot for up to six hours and cold for up to 18 hours. With its compact size and a capacity of 350 ml, it is perfect for everyday use and fits easily under most coffee machines. Of course, the mug is free from BPA and other harmful substances, making it 100% safe. The combination of elegant stainless steel design and the classic red color makes the insulated mug a real eye-catcher. It is also available in black, silver, dark blue, kiwi, purple, and light blue.
