I heartily agree with Bill. Jeff Powell's Rotacrylic blanks are "new life" to penturning !!!!
.... the absolutely stunning surprise you get from turning these blanks is spectacular ...
Pictures don't show the effect, but if you want pictures, I posted a pic of 7 pens I made here:

You *HAVE* to turn one to see the almost miraculous transformation from a kinda ho-hum exterior to the sparkling, iridescent internal beauty. Jeff Powell makes several dozen different imaged designs and everyone gives a different surprise.
As Bill said, they turn easy ... like butter ... and they polish beautifully ... no CA or finish coat needed. Just go through the grits from 320 up to 2000 ... or use micromesh to go even further but 2000 is enough ... wet sanding suggested, then polish with Novus or any plastic polish.
Check them out at Exoticblanks.com, under Guest Artists, and then Master Scroller ... or do a site search for Rotacrylic.
Ask ed4copies about Rotacrylics ... he'll talk your ear off !!!!
They are not cheap, but they are worth every penny. You get 2 blanks with a $22.00 outlay. One blank has an engraved/backfilled image on it (see my picture); the other blank has matching colors but no image ... blanks are about 4.5" long. So you can do a 2 barrel pen, or two single barrel pens (one with image, matching one without image). I like to do them on single barrel kits, like the Vertex ... just the right size to show off the image ... and then use the other color-matched blank to make something else like another pen or a couple of key chains or a couple of seam rippers. The image blank is partially drilled for a 3/8" tube and you should drill that size from end to end first. But you can up the size after that, and make many styles of pens based on 3/8" tubes, 27/64" tubes, 12.5mm tubes, and on up. These blanks would not be good for slimlines or 8mm styles.
