Rinse every item before using them for the first time.
The double-walled glasses are dishwasher safe.However we recommend cleaning the products by hand.
Use standard washing-up liquid for cleaning, do not use coarse detergents like scouring powder or steel wool.
Do not subject the glasses to extreme temperature fluctuations.They can shatter due to pressure,impact or temperature fluctuations.
Never place the glasses on a heat source.

Ideally,use wooden or plastic spoons in the double-walled glasses,as metal spoons could break the glass.
When putting ice cubes in the glasses,always put liquid in first.
