Our cup holder-friendly 30oz and 40oz straw tumblers are anything but copycat tumblers. The Era is a 100% leakproof straw tumbler with a handle, designed for worry-free sipping throughout the day. Our patented Ü-Turn™ leakproof straw lid has three modes for stress-free sips and easy cleaning: open, locked + 100% leakproof, and centred for straw removal.
