The Bormioli Rocco Rock Bar is a robust drinking glass designed for versatility in busy environments. Crafted in Italy from tempered glass using a rapid surface cooling process, these 170 ml vessels are built to withstand thermal shock and accidental impacts, making them safe for both hot and cold beverages. Their thick-walled, heavy construction provides a sturdy feel in the hand, while the 6.9 cm diameter and 8.3 cm height ensure a compact footprint. To help you save space in your cabinets or on a service counter, the glasses are fully stackable and can be cleaned easily in a dishwasher.
