Why this mug earns its place
Glass mugs signal quality in a way ceramics alone cannot—especially when they are built well enough to survive a commercial dishwasher. Arcoroc's Opal range uses fully tempered glass that is chip and break-resistant by design, not compromise. A 250 ml capacity hits the sweet spot for a full coffee service without overshadowing the cup itself, and the stackable format means you're not managing a sprawling footprint in storage.
The Opal range reads as porcelain to a guest—a softer visual than heavy clear glass—but tempered glass gives you protection against the reality of commercial use. Each mug is individually stackable, so you can build a tower in the pass without complex handling. The set of six makes replacement and rotation simple: a mug that cracks gets removed, and you reorder a single box rather than losing a whole set to a single breakage.
At 89 mm high and 72 mm diameter, the proportions are comfortable in hand and quick to clean in a busy service. Dishwasher safe and 100% recyclable, they align with venues moving toward sustainability without sacrificing durability or aesthetic.
