“Always do sober what you said you’d do drunk. That will teach you to keep your mouth shut” - Ernest Hemingway. This whiskey quotes glass makes a wonderful gift for whiskey lovers or anyone who appreciates top-quality products. Our engraved whiskey glasses include a wonderful collection of whiskey lovers and bourbon drinkers’ quotes as well as motivating sports quotes.

All of our glass and crystal products are manufactured by sand-carving. Sand-carving involves using compressed air to force a stream of abrasive through a nozzle and onto the glass to etch or carve a design. Versatility and superior end results are the primary reasons for choosing this method for personalizing glass products. Glass is dishwasher safe.
