Our CARRY Glasses are sturdy, unique, and dishwasher-safe drinking glasses. They are the result of an upcycling process of our CARRY Bottles, as we simply cut our defective drinking bottles into glasses. Available in a set of 2 and in sizes 300 & 400 ml. Manufacturing process - the defective CARRY Bottles are scored at the predetermined breaking point with a diamond cutter - then gas is introduced to build up pressure and obtain the two halves - subsequently, the glasses are ground on the grinding plate and flamed Advantages - products that would otherwise be unusable get a second chance - resource-saving: we save energy - dishwasher-safe - genuine unique pieces The glass should be cleaned regularly and before first use. Before pouring hot water, preheat and cool down slowly. In case of breakage, there is a risk of cuts, therefore it is not suitable for children under 3 years.
