The word guarantee originally comes from the French and means something like "guarantee / security." What we do with our "13 year guarantee" I mean that we vouch for the quality of your unique piece for 13 years from the time of production. In the event of damage caused by quality defects, you will receive a one-off replacement within this period or we will repair your one-off free of charge. Just to make sure you'll have some of your shine for eternity. To claim your guarantee, simply send us an application via our contact field and you will get an answer within 24 hours.
