Ergonomic, stackable, toughened and minimalist, these Arcoroc Log tumblers are great for establishments looking for a smart glassware solution. The tumblers are made from extra-resistant, fully tempered glass. This special treatment ensures they can handle thermal shock without cracking or breaking. And for added peace of mind, even if a breakage occurs, the glass shatters into small, smooth shards for safety. They are also dishwasher safe, allowing for a quick turnaround of fresh glassware during service.
