Fill it with CA , or allow it to fill with grime . Those are the choices .
This is a myth (unless you are David Abernathy and frequently use the pens to perform open heart surgery :wink
. I have engraved and colorfilled thousands of pens. I have a couple of these on my desk that are used regularly and travel with me. I also see many of the other pens when I visit with my customers. I have yet to see any grime in the pens. Nor have I seen any grime in non color filled engravings.
Jewelery, signs, trophies, name plates, name tags, and other engravings are not filled with CA, lacquer, etc. and do not collect grime.
