WMF actually stands for quality and high-class design in kitchen undHaushalt, as far as I can judge it. And this quality can also pay stehts the company. But of this wine closures I have a set of 2 presented within my family and it was a disastrous result. The closures were apparently attacked and survived even with the best care is not the first month of the acids of wine (normal good wines). THE ENTIRE SILVER COATING IS COMPLETELY exfoliated. AFTER YOU gradually into shattered pieces. Just unbelievable! I'm going as fast draw any more articles from WMF safely into consideration.
