Many new cars nowadays do not have an ashtray. This product is an ashtray in the form of a cup with a hinged lid. When the lid is opened you have an ashtray. There is an area inside to extinguish the butt and also a slot to hold the lit cigarette when it is not in your hand. When the lid closes, a rubber seal prevents any smoke from an improperly extinguished cigarette from escaping. The unit is designed to sit in any spare/convenient cupholder in a car or RV. It can also be carried as a personal ashtray as well.
