Zak Designs Harmony Tumbler

Thanks to its double-wall vacuum insulation, this tumbler is designed to maintain your beverage's temperature for several hours. While exact times vary based on the starting temperature and how often the lid is opened, it is highly effective for standard commutes and office use.

The slide lid is designed for convenient, splash-resistant access to your drink. However, it is not 100% leak-proof, so it is best to keep the tumbler upright rather than tossing it loosely into a bag.

The tumbler features a tapered base design intended to fit most standard vehicle cup holders. Its 20 oz capacity provides a balance between generous volume and a portable footprint.

To preserve the integrity of the vacuum seal and the finish of the cream exterior, we recommend hand washing the tumbler. Using a dishwasher can potentially damage the insulation performance over time.

The handle is integrated into the design, which provides a secure grip for carrying. While it adds a bit of width, the streamlined profile is still compact enough to fit easily on most desks and in standard cup holders.
