As a matter of fact, these cups can be used to store carbonated beverages, except that we do not recommend using them in this way for a long time, as the acid and the stainless steel will cause some chemical reactions that will lead to discolouration of the cups and affect the taste of the drinks.

All the accessories of our brand enjoy free after-sales service, if you receive a set with missing parts, just send your address to contact our after-sales team for replacement.

Stainless steel cups themselves do not mold; mold requires the presence of nutrients, such as residual milk and juice. In addition, moisture that is not dried in a timely manner remains inside the cup for a long time and can produce mold or rust. Because, after cleaning the cup, make sure to dry the cup to store. Please wash the cups promptly after keeping milk juice and other beverages.

We do not recommend using the dishwasher for long periods of time as it can damage the powder coating on the outside walls.

Our cups are equipped with different types of lids, each with different leak-proof performance. If you encounter a leaky lid, please contact our after-sales team to arrange a return immediately.
