Q&A
Q: What is the grease on the surface of the hopper ball?
A: When you open the package, you may find that there is grease on the surface of the hopper ball. This grease is a layer of protective grease, in order to prevent the deflated ball from sticking. Dont worry.
Q: How to deal with it?
A: No need to deal with it. After the hopper ball is inflated, it can be LEFT for 15 minutes in the natural environment.
