These glasses use Onis’s XTRATUFF technology as an additional heat treatment process which is targeted at the rim of Libbey glass, stemware and tumbler products. This process adds significant additional strength, durability and resistance to thermal/mechanical shock, thus helping to extend the life of the glass in a demanding bar and kitchen environment. It’s barware tough.
