wine glass is made with epoxy resin and alcohol ink. The glasses are handmade and showcase the amazing swirling properties of alcohol ink and epoxy. Due to the mixing nature of the alcohol ink with the epoxy, each wine glass it totally unique. The design is sealed with FDA compliant epoxy for a smooth, shiny finish. Each glass that I make is truly one of a kind and is a work of art. The glass is a traditional 30 oz wine glass. Please hand wash. Do not soak in water or put in the dishwasher, microwave or freezer.
