The Perfect Solutions Football Talking Beverage Mug is a glass beverage mug that leads the charge in fan support. Just press the laces on the football voice box that's clipped to the handle to enjoy 5 FAN-tastic, cheer-rousing calls, complete with sound effects. It's the perfect way to crank-up the fun at any get-together or tailgate party. Plus, once you unclip the voice box, the mug cleans easily because it's dishwasher safe. The mug can hold up to 20 oz. and the voice box operates on 2 button cell batteries (included).
