Thank you very much for viewing! Instant purchase and no-comment purchase are welcome! This is genuine lubricant. Regular use as a maintenance agent not only improves the cube's lubricity but also prevents damage caused by dryness and friction. When you feel the cube is moving too smoothly, it helps control the slipperiness, enabling more free and stable cube control. [Contents / Quality Guarantee Period] 10ml / 3 years [Storage Method] Store in a cool, dry, and well-ventilated place. [How to Use] For safety, the cap rotates freely when unopened. To open, firmly press the cap into the groove on the bottle side and slowly turn it counterclockwise. The appropriate amount to use for one maintenance is 1-2 drops to make the cube smooth. If it becomes too sticky due to over-application, wipe off the lubricant. Apply the lubricant into the gaps of the cube and rotate the cube until the lubricant is evenly distributed.
