Černý Chroma Quencher H2.0 FlowStateTM hrnek | 30 OZ

The iridescent band catches the light in a way that shifts from deep purple to green depending on the angle, and the matte black powdercoat feels smooth and secure in my hand. It holds a full 30 ounces easily, so I only refill it twice a day at my desk.

Finally a tumbler that doesn't look boring on my desk—the matte black finish is so smooth, and that iridescent shimmer band catches the light from every angle, making it feel almost custom. Keeps my iced coffee cold for hours and the 30 oz size is perfect for not having to refill during meetings.

The iridescent band shifts beautifully in the light, and that matte powdercoat keeps fingerprints off way better than my old tumbler. Lid seals tight enough to survive a knock in my bag, and the 30 oz size is perfect for my whole workday.
