This is a set of four aura rainbow luster wine glasses with iridescent crystal formations and a Swarovski crystal on the bottom of each glass. The crystals inside are made from non-toxic materials.
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.
