How to install three rolls of collodion mop?

1. Put mop head on the ground and insert the handle into the central hole of mop head.

2. Turn the handle until the buckle is aligned with the protrusion of mop head, and the depth of the handle inserted into mop head cannot exceed the buckle.

Pull the handle to see if it is firm. If it is loose, you need to re-insert the handle.
