After watching Feng Zhu's Gnomon DVDs, I embarked on a quest for the now infamous Pilot Hi-Tec-C pen line, of which he uses in many of his works. A search of Conceptart.org revealed several threads on the topic, so I won't reiterate what was discussed. I have, however, contacted pilot with the intention of finding a similar product line available in the United States(and places abroad).
The following is Pilot's response:
"Thank you for your recent E-mail message. Yes, due to our marketing agreement with our parent company, and in some cases patent restrictions, we are unable to either sell or stock this item.
Each Pilot Affiliate has a specific list of products available to them and the residents of their marketing area. They may not sell outside of their area, nor may they sell directly to consumers. We are sorry to say these pens are unavailable to you unless you travel abroad.
Our Precise PV-5 and 7 would be equivalent to the Hi-Tec. However, we have only .5mm and .7mm available. Nothing smaller is available. These can be viewed on our website www.pilotpen.us under the Rolling Ball line.
If you would like samples sent please supply your complete mailing address and specify your color preference."
Note that only .5mm and .7mm are available. 0.3mm, and 0.4mm are not included in the US product line.
I thought this information would be somewhat valuable to the community, as this matter has posed a considerable annoyance for many of us. If anyone has found a suitable replacement, please post your findings so that we can have this thread as a resource for later user perusal.
I pray that this thread is posted in the proper forum, and I apologize to the Conceptart.org staff if I have posted this thread in error.
Thank you all for your time.
