American White Ash Pen Blanks.
 
These are leftovers from planks I used in the past. The Ash, while pale now will darken slowly over time and become a golden honey colour (depending on what finish is applied) once turned to final size.  My crosscut blade was a bit dull so some tearout is visible, this will be turned away anyway.
 
Suitable for single body or split body pens
 
4 pieces, bandsaw cut and cleaned up with a sanding machine.
150x25x25mm approx
 
Normally, pen blanks are around 20mm x 20mm but I have oversized them slightly to allow for the wood being cut individually from real Irish wood.  The cuts may not be perfectly straight and this gives you more room to adjust if necessary.
