Inspired by the spherical shape of a wineglass, the tumbler is designed. with a continuous spherical shape with a round “plint” like base displaying the shape of the glass. The blown crystal gives a perfect weight to the tumbler being heavier in the bottom and having a very fine and delicate rim that’s comfortable to drink from. The tumbler is made of lead free environmentally friendly glass. that are both durable and dishwasher safe.
