All reusable water bottles and tumblers help reduce waste, but the Harmony Tumbler goes even further by combining quality, functionality, and individuality into one sleek design. The wide handle allows you to carry it in comfort, and the slim shape fits easily into most car cup holders, so you can bring your favorite beverages anywhere your daily adventures take you. Plus, the Harmony Tumbler from zak! features a slide lid that gives you easy access to your drinks while helping to prevent splashes on the go. When it's time to clean up, the slider can be removed to reach every nook and cranny, and the lid and tumbler are top-rack dishwasher safe. It’s amazing how not having to compromise can put a smile on anyone’s face!
