Skill,careful folding,choice of top brand name. Brad that kit enhances your craftsmanship and planning.Filling the pen ,allowing space in the components. Your ability to shape the face,utilise the hands (vital IMHO) is enviable. Us mere mortals can but dream of this success.
I normally refrain from saying this but in the flawed process of pen of the week this pen has a great future. The great flaw is trying to compare with so few participants during the event.
Hands down a magnificent contribution to penmaking.
