Why this tumbler earns its place
These 350ml tumblers from Onis deliver the heft and capacity you need for double measures and long drinks without the weight penalty of inferior glassware. Each glass has been treated with the Onis Xtratuff strengthening process, which hardens both the bowl and the rim against the thermal shock of hot water and ice, and the mechanical shock of service line collisions. For venues with compact bar space, the stackable design is a genuine difference — you can store a week's worth of service glassware in half the footprint. Dishwasher safe and finished in clear crystal, they work equally well for neat spirits, tall cocktails, or soft drinks and mixers.
The distinctive shape of a double old-fashioned sits comfortably in the hand and photographs well on social media when customers catch their moment. Unlike cheap tumblers that cloud and chip within months, these glasses have the staying power to justify their place in a professional kitchen — the Xtratuff treatment specifically addresses bar and restaurant wear patterns.
