摘要

A ball or sphere, consisting of six pieces carved in an irregular shape, so that they fit together, and when they have all been placed, form the sphere, each piece having different faces, with their corresponding edges that fit perfectly with others so that when the sphere is constituted, if the adjustment is well done, the lines that appear on the surface of the sphere are barely perceptible, in order to constitute a true puzzle that can be used for instructive, patience or advertising.
