Buyer questions

Q: Does the thermal coffee mug keep drinks cold?
The product is optimized for hot drinks and is excellent for heat retention. It can also be used for cold drinks, but if you want maximum cold retention, we recommend special cold-adapted mugs with additional thermal insulation layers.

Kl: How to maintain and clean stainless steel?
The thermal coffee mug is easily cleaned with cold or warm water and a small amount of soap. You should wash both the inside and the outside. Never use aggressive cleaners, as they may damage the steel. Allow it to dry naturally or wipe it with a dry cloth.

Orders are shipped within 5 business days. Delivery time depends on the country and may vary due to weather conditions and holidays. We provide a full refund if the product does not match the description or is damaged. Please contact our customer service first.
