Anti-spill mug


This is the perfect cup for a rocking boat while at sea! These 16 oz. insulated plastic mugs are designed to never fall over and spill, with rubber stoppers on it's wide base to prevent sliding across the table and on to the floor. Comes with a removable lid for keeping your coffee warm all morning! We use these mugs for everything we drink while out for days at a time on our Shark Expeditions!
