The Corally bearing oil comes in a new bottle. The bearing oil is to lubricate bearing and bushings and any other stuff you want to lubricate. The opening of this special bottle is very sophisticated. You turn it counter clock-wise, you can adjust how much you want to open thus also the speed of how quickly you want to dispense the fluid out of the bottle. That means you can lubricate very fast and a lot, or very slowly and little. If you turn the opening clock-wise, you close it tightly shut. No leaking whatsoever. Trust me, once you use this bottle, you will never want to use any other bottle again.
