Yes, a coffee ink pen. The body is is composed of real coffee beans in a white matrix. I do not think it is acrylic, too soft. After I turned the pen, my workshop smelled like coffee. I gave it a few coats of catalysed urethane to seal the coffee beans and give it a nice shine. Interesting stuff, and yes it was a little difficult to turn.
Very nice, Dave. I like it. The white/cream color really sets off the beans, and one has to take a second look to see that they actually are real beans...
Now, if you can do it with a fountain pen, and distill your own ink from espresso....
Just for fun. I do have one guy that buys them from me and resells them on his web page.
That is my cappuccino pen. I should change the barrels and put a fountain tip in it then pick up some brown ink just for fun. I wonder when the roasted on date was?
