Has anyone ever purchased or used this? I was looking at this product and was curious whether it was safe for the rest of the barrel as well. Or why it was marketed as only for the nib and feed...?
Was also curious about the viability of this cleaning solution for vintage pens (thinking of using it on Montblanc 22/24/31/342/Monte Rosa)
