Set of four 16-ounce pub glasses. Deep etching is a glassware and ceramic sand-carving process that produces the most beautiful and long-lasting etched design. Deep-etched by hand using today's technology with a technique that has been around for centuries. You can use them with confidence that their design and beauty will last through generations. Unlike designs created using chemical or acid etching, these designs will not wear off through everyday use or cleaning, even in industrial or residential dishwashers.
