Ariel Kullock is an Argentinian innovator, artist and customizer of fountain pens. He has been making customized pens since the 1990's, including Parker 51s with new barrel and section pieces as well as custom caps and entirely re-worked Parker 51 "fantasy" pens.

This particular pen is an original Parker 51 which we have stripped down and restored in house and fitted with a transparent hood and barrel, making this iconic pen into a transparent "demonstrator". 

You can see all the wonderful details which make the Parker 51 great, the aerometric filling system, intricate collector and slim feed - even the shellac which seals the grip section!


The fountain pen is in excellent condition.


The original Parker 51 was stripped and fully restored and then fitted with new old stock parts direct from Ariel. 

All our pens come Grand Vision Guaranteed: guaranteed to write beautifully out of the box and to provide long lasting writing service.


There are no major imperfections to note, no chips cracks or engravings

The pen has only light sings of wear, micro-scratches present on the barrel from storage, and the cap shows signs of use, but is entirely ding free. 

A superb pen

Writing Style & Nib Appraisal

The nib has been tuned to ensure smooth writing experience.

The nib is a Stub Nib


Recommended for everyday use, calligraphy, greeting cards, signatures, journaling, and all forms of appropriate use. 

Why not pair with a bottle of Organics Studio Ink - one of the vintage range would suit this pen very well!
