Abstract: A rolling device, a package for rolling device and a rolling module are introduced. The rolling device includes a receiving seat defining a receiving recess, at least one secondary rolling member received in the receiving recess to contact with a surface of the receiving recess, a primary rolling member partially received in the receiving recess to contact with a surface of the at least one secondary rolling member, a coupling section connected to the receiving seat for coupling to an external object, and a stop section connected to the receiving seat and defining a stop opening, which has a size smaller than a maximum size of the primary rolling member.
