Inverness glassware by Libbey/ ONIS features a pentagon base that is a perfect alternative to typically conical tumblers and ideal for adding a modern and contemporary flair to drinks presentation. 

Made from Libbey’s DuraTuff treated glassware, designed to strengthen the upper portion of the glass, increasing its resistance to thermal and mechanical shock. 

The ONIS Xtratuff treatment is applied to the upper half of the glass, adding toughness, durability and resistance to breakages. This process also reduces wear and tear of stackable glasses, helping to meet the highest professional standards in glassware.
