The oilcup, made of bone-colored buffalo horn, has its own kind of cover and oiling brush. The oilcup made of buffalo horn, used to lubricate the wheels of ox-cart during World War.

In ancient times, instead of motor vehicles, there were wheeled cars that moved with animal or human power. This vehicle, known as the cart, used to walk with at least two wheels. But since the power applied to the car was given by humans or animals, the wheels had to be constantly lubricated so that they could rotate more easily and conveniently. For the oil used in the lubrication of the wheels, the horn was preferred to be make an oil from it, since it was large and suitable for processing.
