Amici's mouth blown, hand made Mexican Rainbow Cooler or Hiball Glass is produced using recycled glass. It takes several craftspeople to make each piece. After the glass is blown into shape, the glassblower twirls the piece while each color is hand applied by a different artesian. The result is a greenish glass with an amazing band of color around the middle. It is a labor intensive process that can only be done in Mexico. Each glass is 5.1 inches tall by 3.1 inches wide with a 16 oz capacity. Expect slight variances in height and width due to the handmade nature of this glassware. Dishwasher safe .
