Set of 6 Crystal Highball Water Glasses

The glasses were beautiful when they arrived and the colors were very nice. Having the variety meant the family members could have different colors and know which glass belonged to which family member. Unfortunately, three months after purchase the blue glass started having issues with having a roughness on the side. At first I thought it just needed better cleaning. A couple weeks go by and now it appears that a film is coming off and making the glass look worse and worse. I don't know if there was a problem with just the blue batch or if it is going to happen to all the glasses but this does tell me that quality control has a problem and is not consistent. It is past the return date so I cannot get a replacement. I had thought about getting a second set but with this problem I may have to find some other brand with something similar.
