THE WORKING VIEW

Why this hi ball earns its place

The Onis Endeavor range ticks the box for high-volume service — 350ml capacity sits cleanly between highball and tall-drink needs, and the 75mm diameter balances grip comfort with bar density. A pack of 12 gives you baseline stock for three shifts without constant washing or stock rotation headache.

Onis's Xtratuff treatment is the real differentiator here. It's a chemical-hardening process that raises the glass's resistance to thermal shock (ice water to warm dishwasher spray, or iced spirit to room-temperature service) and mechanical shock (dropped on a stainless-steel bar top). That translates to fewer stems snapping mid-shift and glassware that survives thousands of cycles instead of hundreds.

Stackability matters in tight bar spaces — you can store a pack and a half in the footprint a non-stackable design would need for three quarters of one. Dishwasher safe finish means they go straight from draining rack to machine on high-temp cycles without fear of etching or damage.

BEFORE YOU BUY

Questions, answered straight

The Xtratuff treatment hardens the glass against both thermal and mechanical shock, so they're more durable than standard tumblers. They're not unbreakable, but they'll survive dropped ice, collisions with bar steel and being grabbed quickly mid-service far better than untreated glass.

Yes — the thermal shock resistance is exactly designed for that. You can pull them from a chiller, hand them to service, and they go straight into a 65°C commercial wash cycle without risk of cracking from the temperature change.

They stack neatly one inside the other, which saves space. A full pack of 12 stacks down to roughly the footprint of a single glass at full height — useful for tight bar storage or pre-service prep.

Xtratuff treatment includes the rims, so they resist chipping better than standard glass. They won't chip-proof themselves under real bar use, but they'll last longer before the rim becomes rough or unsafe.

Onis specifies these as dishwasher safe — they're designed for commercial high-temp cycles at 65°C+ without issue. Check your dishwasher manual, but these will handle standard commercial-kitchen wash temps.

No — treat them like any commercial glassware. Stack them, wash them hot, store them anywhere from cold display to room-temperature racks. The Xtratuff process is baked into the glass itself, not a coating.
