I make and sell a whole range of Rollerball pens. All of them have Parker inserts and mechanisms. I stock Classic and Orion and can do them in silver or gold finishes. Add to that as well that both the Classic and Orion can also be fountain pens and you will see that there are eight possible pens in this range – that’s before we get to the wood and finishes!
Pictured here are two of the classic silver designs (my favourite) made with Laburnum and African Blackwood. Both classy, executive, smart!
The Classic – this has a screw off cap which can be added to the other end of the pen, but this adds weight to the writing.
The Orion – again a screw off cap, but this will not fit onto the other end. 
Turned Out Nice
