A plurality of pens or other marking implements is provided. They are set forth as a minimum of two, but by the simple technique of altering the reservoirs, the colors can be substituted almost infinitely. There are two for each implement, and these can be multiplied in two by changing the ink devices. Other changes can be made by duplicating the implements or writing pens, which come in pluralities of two. Adjacent pairs are locked together by shaping of the base, and the pens can be duplicated in initial savings by the colors chosen, and the number of pens can be duplicated depending upon the shape of the devices which are made to be interlinked by joining of the bases, and by the self-return of the base station from which the pens originate, the pens being joined to the base station by flexible links of indeterminate length.
