CoffeeCups cups are made of high-quality 304 stainless steel and have safe silicone lids. All materials are food-safe.

Although the mugs are very durable, washing them in the dishwasher can weaken their insulating properties and damage the protective coating, so we recommend handwashing. After each use, simply rinse the mug with warm water and dish soap—preferably using a soft sponge or a dedicated mug brush.

CoffeeCups, while not typical thermal mugs, feature a double-walled base that helps maintain the temperature of your beverage for longer. The exact time it takes to keep your beverage hot or cold may vary depending on conditions, but it typically stays at its optimal temperature for about 1-2 hours.

Yes, we offer personalized mugs, but this involves additional costs and longer order processing times. If you're interested in more details, we'd be happy to prepare a personalized quote.

Our returns and complaints policy is detailed in the "Returns and Complaints" section of our website. We encourage you to review this information to understand all terms and procedures.
