Wax painting pen has wax core enclosed by paper, cardboard or plastic circles, with sleeve or bridge piece, end and front circles

摘要

Circles (4,5) of paper, cardboard or plastic enclose the wax core. The circles are spaced apart or are joined by a bridge. A paper sleeve or bridge-piece (2) is stuck around the rings and may be closed or possess an axial slit (6). The back end of the wax core has a circle fixed to it; a front circle sits on the core leaving clearance.
