Frequently Asked Questions
Q: What makes 316 stainless steel better than 304 stainless steel for a tumbler?
A: 316 stainless steel contains molybdenum, which gives it superior corrosion and rust resistance compared to standard 304 stainless steel. This means it's more durable, especially when used with acidic beverages like coffee, juice, or sports drinks, and it imparts absolutely no metallic taste or odor to your drinks.
Q: How long does the 720ml vacuum tumbler keep drinks hot or cold?
A: Thanks to its double-wall vacuum insulation, this thermal flask keeps hot drinks warm for up to 12 hours and cold drinks chilled for up to 24 hours, depending on the ambient temperature and how frequently the lid is opened.
Q: Is this stainless steel tumbler dishwasher safe?
A: To preserve the vacuum insulation and finish, hand washing with warm soapy water is recommended. Avoid submerging the lid mechanism in a dishwasher as high heat and strong detergents can degrade the seal over time.
Q: Can I use this tumbler for both hot coffee and iced drinks?
A: Absolutely! The double-wall vacuum design works equally well for hot beverages like coffee, tea, and hot chocolate, as well as cold drinks like iced water, juice, smoothies, or sports drinks — making it a truly versatile everyday tumbler.
Q: Is this a good gift option?
A: Yes! With its large 720ml capacity, premium 316 stainless steel build, and stylish design, this thermal tumbler makes a fantastic gift for coffee lovers, fitness enthusiasts, office workers, travelers, and anyone who appreciates staying refreshed throughout the day.
