DuraTuff Treatment

Thanks to a special thermal after-process applied to the top portion of the glass, you can rest assured that it has exceptional durability to match its looks! This DuraTuff treatment is designed to increase the glass's resistance to mechanical and thermal shock while also making it safer to use. When a normal glass breaks, it typically shatters into tiny pieces that can cause harm to customers and staff, contaminate food, and create downtime as your staff cleans up every little piece. DuraTuff glasses, on the other hand, tend to break into larger pieces, shortening cleanup and making them a much safer alternative for everyone in your restaurant or bar.

Thick Sham

With a thick sham for added stability, this glass is perfectly balanced to rest on trays, tabletops, and counters.

Crystal-Clear Clarity

Crystal-clear clarity also showcases each drink to enhance your presentation, adding sophistication to any table setting.

Libbey Brand

Since 1818, Libbey has been a leading distributor of glassware, providing a wide selection of durable and elegant products to suit your many needs. In that grand tradition, the high-quality form and feel of this Gibraltar rocks glass make it a perfect addition to any restaurant, hotel, or bar.

I always get these & and always like the style and that they are stackable. Although this time multiple glasses were broken at delivery. I'm not sure if it's because I had delivered to my home instead of business. It seems that deliveries to my home are usually damaged. I recommend having shipped to a business as those delivery people tend to handle with care.

Thank you for your review, Tammy! We are sorry you've had shipping issues with these glasses. A Customer Solutions Representative will contact you soon!

Will definitely buy again. This is the same glass I have used in my bar for over 10 years and it never disappoints. Thick and durable glass and good value. The only problem was they arrived broken and had to be replaced at webstaurant"s expense and was replaced at lightening speed!

Solid Gibraltar glass. We use these for self serve water glasses and cortado espresso beverages at our shop. The only reason why I don't give it 5 stars is because I wish it was a little heavier.

We use these for Lambrusco where the facets really show off the colors. And we pop them in the freezer to serve limoncello after the meal. Their heavy weight makes them frost beautifully.
