The handy, machine-made Riedel O Wine Crystal Tumbler Glass for Single Malt Whiskey of the space-saving glass collection by Riedel attracts attention through its stemless design. The stemless design makes it less susceptible to glass breakage and easy to put into the dishwasher. The design incorporates a small, slightly out-turned lip that directs the spirit onto the tip of the tongue, where sweetness is perceived, and serves to bring out the elegant creaminess of a top-quality single malt. This premium tumbler is the ideal glass for everyday use and for every occasion. It is fun, feels good to hold, looks trendy, and it works! This pack contains two glasses, so don't be afraid to share some libations with a friend or family member. These glasses are dishwasher safe.
