ABSTRACT:
A spinnable top comprises a flywheel component and a spindle component which are readily adapted to assembly and disassembly by reason of mutually threaded engagement to a shoulder stop. As a kit, these component parts and a wrench component, for use in torquing the assembly and/or disassembly, are retained in the base of a two-part thin cylindrical container; the other part of the container is a selectively removable cover which is configurated as a concave area by means of which each run of the top can be limited.
