Why this tumbler earns its place
The double old-fashioned is the shape that refuses to age out. The Onis Cheers version, at 350ml and 96mm tall with a diameter of 91mm, is built to the proportions that made the format enduring: wide enough to work with ice and spirit, tall enough to accommodate a mixer without spilling, substantial enough to feel right in the hand. The vintage cut-glass aesthetic — those geometric panels styled on 1940s–50s glassware — gives the classic form real character without pushing into novelty.
The 350ml capacity sits in the middle ground. It's larger than a proper rocks glass (300ml and under) but stops short of a full tall tumbler — enough room for spirit, ice, and a honest pour of mixer (tonic, cola, ginger beer) without the glass feeling half-empty. The 96mm height means these glasses don't dominate the bar top but aren't undersized either. The wide, open mouth is stable during service and allows proper ice integration. This is a glass that works across the menu: Old Fashioneds, yes, but equally good for a Negroni, Sazerac, or simply a spirit and mixer.
Dishwasher safe and sold in packs of six, they're built for the pace of service. The form is simple and robust — no delicate rims or thin stems. The vintage design reads as intentional glassware choice rather than generic house stock, which matters when price-per-drink is a consideration. For venues balancing quality service with commercial reality, this is the kind of glass that pays for itself through customer perception.
