Also, possibly available from C & R Loo (the glass rods, not the kit).
Edit: They used to carry the kit and the ribbed cane, but you'll have to call for availability and pricing. After their move, they only seem to have any Lauscha that is left in the warehouse. The old part number for the pen kit was L-KIT2 and the description of the cane is here

Fire Lady might be able to special order the colored ribbed cane, if you have her a description. C & R Loo might be able to special order it also (if no longer in stock), since they have offices in Germany.
C & R Loo contact information is at the following link. (the
http://130.94.190.116 is the site for their old catalog). The glass in the picture is their stock of Lauscha tubing, at least it was from a couple of years ago.
