40oz Stainless Steel Vacuum Tumbler with Leakproof Straw

A: This tumbler is available in 30oz (887ml) and 40oz (1183ml) capacities. The 30oz version measures approximately 7.5 inches tall with a 3.5-inch base diameter, while the 40oz version is about 9 inches tall with the same base diameter. Both feature double-wall vacuum insulation.

A: Yes, the included straw lid is designed with a silicone gasket and a snap-closure mechanism that seals the straw opening when not in use, preventing leaks even when the tumbler is tipped or placed in a bag. However, if you remove the straw, the lid itself remains leakproof only if the straw hole is covered by the built-in sealing flap.

A: The tumbler body is made from 18/8 stainless steel (food-grade, BPA-free), and the lid is constructed from durable, BPA-free plastic with a silicone gasket. It is safe for both hot and cold drinks. Do not microwave or freeze, and hand washing is recommended to preserve the vacuum seal and finish.

A: The double-wall vacuum insulation keeps beverages cold for up to 24 hours (when pre-chilled) and hot for up to 12 hours (when pre-heated). For best results, pre-condition the tumbler with ice for cold drinks or hot water for hot drinks before filling.

A: Yes, this tumbler is customizable. You can choose from multiple color options for the body and lid, and we offer laser engraving or full-color printing for logos, names, or artwork. Minimum order quantities may apply for custom designs, typically 50 units. Contact our sales team for details and pricing.

A: We offer a 1-year limited warranty against manufacturing defects, including vacuum seal failure, lid cracking under normal use, and finish peeling. The warranty does not cover damage from misuse, drops, or modifications. Replacement parts (lids, straws) are available for purchase separately.

A: Yes, we ship worldwide. Standard shipping within the US is free for orders over $35, with delivery in 5-8 business days. International shipping rates vary by destination and weight, with estimated delivery times of 10-20 business days. Customs duties and taxes may apply and are the buyer's responsibility.

A: Yes, each tumbler comes with a reusable, BPA-free plastic straw. The straw is designed to fit snugly but can be removed for cleaning. We recommend using a straw brush to clean the interior, and both the lid and straw are dishwasher safe on the top rack, though hand washing extends their lifespan.
