This is a set of two or four aura rainbow luster stemless glasses with iridescent crystal formations. The crystals inside are made by designer Kelly Cimber from non-toxic materials.  Check out the matching wine stoppers. 

Great for clear drinks like white wine, rose, champagne, water, and soda water mixed drinks. Does not work best with red wine, as you can not see the crystals and will make harder to clean. Recommended for hand wash only because of the aura coating, each set also comes with a cleaning brush.
