A large number of people are used to drinking coffee everyday, but sometimes it is not convenient to take a spoon with us for stirring coffee.
We solidify coffee powder into a stick to make the Bar Coffee. People stir the water with the Bar Coffee, which makes it melt gradually. A cup of coffee is made in a minute without using a spoon or something else. The Bar Coffee meets people's living habits while it is convenient and portable. Where there is a cup, we can have a drink of coffee.
