Custom Insulated 304 Stainless Steel Coffee Mug 12oz 16oz Coffee Mug with Lid

Q: What sizes are available for this insulated coffee mug?
A: This mug is available in two sizes: 12 ounces (355 ml) and 16 ounces (473 ml). Both sizes feature the same modern design and 304 stainless steel construction.

Q: How long does the mug keep drinks hot or cold?
A: Thanks to the double-wall vacuum insulation and 304 stainless steel, hot beverages stay hot for up to 6 hours and cold drinks remain cold for up to 12 hours. The exact duration depends on the starting temperature and ambient conditions.

Q: Is the lid truly leakproof, and can I use it in my car?
A: Yes, the lid is designed with a silicone gasket and a secure lock mechanism to prevent spills. Its slim base fits most standard car cup holders, making it ideal for commuting or road trips.

Q: What materials are used in this mug, and are they safe?
A: The body is made from premium 304 stainless steel, which is food-grade, rust-resistant, and free from BPA and other harmful chemicals. The lid is constructed from durable polypropylene with a silicone sealing ring. All materials meet international food safety standards.

Q: Can I put this mug in the dishwasher or microwave?
A: We recommend hand washing the mug with mild soap and warm water to preserve its insulation and finish. The stainless steel body is not microwave-safe. The lid is dishwasher-safe on the top rack, but hand cleaning prolongs its lifespan.

A: Yes, this mug is popular for corporate gifts and promotional events. We can add your company logo or custom text through laser engraving or screen printing. Minimum order quantities may apply for customization. Please contact us for details and pricing.
