To prevent tipping, the Libbey 15141 pint glass is built with a weighted base that secures it to a table top or bar. Built with a DuraTuff® glass construction, it's heat treated to prevent breaking when exposed to cold temperatures, and if it does break, it breaks into manageable pieces rather than shattering. It's clear construction improves the presentation of beer held inside and indicates to bartenders when a refill should be offered. This glass features a 14-ounce capacity and can be placed in a dish machine after use.
