The Onis Endeavor Double Old Fashioned Tumbler is a commercial-grade rocks glass designed for bar and beverage service. At 350ml, it sits comfortably in the double old fashioned format — well suited to spirit serves, cocktails on the rocks, and soft drink covers alike. Supplied in a pack of twelve, it is a practical choice for operators stocking up or replacing attrition losses.

Onis treat these glasses through their Xtratuff process, which improves resistance to both thermal and mechanical shock. In a busy bar or restaurant environment, that translates to a glass that holds up better against the rigours of service — rapid temperature changes from chilled ice, repeated handling, and commercial dishwasher cycles. No glass is unbreakable, but treated glassware of this type tends to last meaningfully longer than untreated alternatives under the same conditions.

From an operational standpoint, the Endeavor range offers a few practical advantages worth noting:

  • Stackable profile helps manage storage space behind the bar or in glass storage areas
  • Dishwasher safe, supporting efficient turnaround between covers
  • Consistent shape and capacity simplifies portioning and presentation across a team
  • Pack-of-twelve supply suits standard glass rack sizing

These tumblers are a straightforward fit for bars, pubs, casual dining restaurants, and hotel beverage operations. For very high-volume venues running multiple sittings or large event covers, it is worth considering whether a larger initial quantity better suits your breakage and replenishment cycle.

If you are building out a full glassware range or want guidance on quantities relative to your cover count, the team is happy to help you work through it.

Frequently asked questions

How many packs would a typical bar need to hold as standing stock?

A common guideline is to hold two to three times your peak cover count in glassware to allow for glasses in use, in the wash, and in storage simultaneously. For a busy bar running 40 or more covers, two or three packs of twelve as a baseline is a reasonable starting point, adjusted upward if your service is fast-paced or breakage rates are high.

Will these glasses hold up in a commercial glasswasher used several times a day?

The Xtratuff treatment is specifically intended to improve resistance to the thermal shock and mechanical stress that commercial glasswashers introduce. As with any treated glassware, following correct rack loading and avoiding overloading the machine will extend glass life further.

Are these tumblers suitable for both cocktail service and standard soft drink covers?

Yes — the double old fashioned format is a versatile shape that works well across spirits on ice, cocktails, and non-alcoholic serves. Its broad base and generous capacity make it a practical all-rounder for mixed bar menus rather than a specialist glass for a single serve type.
