After I was startled violently looking for an everyday harness if the price of a good service, I decided to buy a simple dishes at the discount that but after a short time silver scratches exhibited by cutlery contact on the otherwise white plate. By chance, I became aware of this tableware. I can not comment, but after about 2 months to see the dishes still like new and have no scratches on the long-term use. The porcelain is quite stable. I have now three sets, so I still have some marbles despite dishwasher use ;-)
