It is a maintenance oil for the yo-yos of the yo-yo maker YOMEGA.

Although it is originally for yo-yo, it can be used for Diabolo using bearings such as San-Vinlin or Ferrin bearing type as well.

Let's put in oil when a high sound is heard when Diabolo turns.
By inserting a small amount into the ball bearing between the bolt and the clutch bearing, the rotation becomes smooth and the life of the bearing dramatically increases.

When using, please cut with the tip with scissors, nippers etc.
