SIPP travel mug with hygienic lid by JOSEPH JOSEPH. Reusable cups often collect dirt and germs from being carried loose in a bag or backpack, but also when handled by waiters in cafes if we order a drink. However, this clever design features an airtight flip-top cap that, when closed, completely covers the mouthpiece, keeping the area in contact with the lips much more hygienic. Constructed of heavy-duty BPA-free plastic and featuring an airtight screw-top lid to prevent spills and a soft-touch finish that provides both a non-slip grip and an extra layer of insulation when holding hot beverages. Now you can enjoy your favorite drink on the go while helping to reduce the use of disposable plastic cups.
