Elements which connect together

摘要

A set of combined construction toy and marker bodies. Each marker (50) includes ball portions (58, 60) and socket portions (62, 64) that receive the ball portions (58, 60). The construction facilitates a pivoting, rotatable interconnection between markers. All of the markers (50) may also consist of an identical shape. Each marker (50) may further include a separable cap (54) that incorporates a ventilated end (132) to allow fluid passage therethrough, so as to provide an air passageway (130) through the cap (54).
