Whaline Tumbler

The double-wall stainless steel construction is designed to maintain beverage temperatures for several hours. While performance can vary based on the starting temperature and ambient conditions, it is effective for keeping coffee warm during a commute or iced drinks chilled throughout the afternoon.

The lid is designed to be spill-proof, which helps prevent accidental messes during normal use. However, it is not fully leak-proof, so it is best to keep the tumbler upright rather than tossing it loosely into a bag.

The set includes a dedicated cleaning brush, which is essential for scrubbing the inside of the reusable straw. For the tumbler itself, we recommend hand washing with mild soap to preserve the integrity of the festive watercolor design.

Yes, the 21-ounce size is designed with a tapered base that fits comfortably in most standard vehicle cup holders, making it a convenient choice for travel.

The watercolor design is durable, but like most printed drinkware, it is susceptible to wear if subjected to harsh abrasives or high-heat dishwashing. Hand washing is the best way to ensure the pumpkin and flower pattern stays vibrant over time.
