The Gans Lube come in a 10ml plastic container. It makes a huge difference in any cube. The lube comes in a clear bottle with a tamper-proof cap.
Instructions on the bottle:
"Please lubricate the cube before it becomes dry. A badly lubricated cube will not only give loose or resistant hand feel, but also be damaged over the long term. Please start with only 1-2 drops. Add drop by drop if it's not enough. Too much oil will make the cube too sticky. Drop the lube from the gap into the cube. Turn the cube until the lube is evenly distributed."
