Elephant Couple Whiskey Glass Set of 2. The number 14 is in the heart. Glasses are 11.2 Ounces. Dishwasher Safe.. Each glass is sand blasted. Photosensitive masks of each design are created and hand applied to the surface of each glass in the preparation for Wulf Creek Designs to then sand blast them...one-by-one. High pressure sand is sprayed through a nozzle to slowly etch away the surface. The sand blasting process creates amazing detail in glass and a deep cut design which you cannot get with laser etching. It will not fade or wash off making it dishwasher safe and requires no maintenance to preserve the etching - it's permanent!
