Sweet pen! Where did you get it, if you don't mind me asking?
$45 for either the carbon fiber or leather model, $38 for the rest. (seems to be about $5-6 for shipping, and they ship from whatever authorized retailer is closest to you, mine was shipped from some Business Stationary Store called The Appointment in Ohio).
The only thing they won't tell you though, is that a converter does not come with the pen. Does come with a empty cartridge (Without a bottom) which is good for cleaning, as well as a spare cartridge sitting at the bottom of the barrel.
Also most standard international converters won't fit, the barrel is too narrow (I heard from some others this happened later on, to make it where converters can't fit if it's not as thin as a cartridge), and the option to buy a converter with the pen wasn't available.
After voicing my complaint about this, since I like to use bottled inks (I'm currently using a large waterman intense black cartridge), I got this response back from Faber-Castell:
Dear Mr. Blessing:
Thank you for your interest in Faber-Castell and the Design Brand.
I'm sorry to hear of the difficulty you experienced. Our Design Brand pens only accept Item #148785, $5.00 - this item is available for direct purchase at this time as it is not currently listed on the website. We are currently working to correct this. Additionally, Faber-Castell ink can be purchased in bottles or cartridges directly from our website at the following direct link:
In the meantime, I have posted a converter to your attention at no charge for the inconvenience. Thank you again for your interest in Faber-Castell and the Design Brand. Please let me know if I can assist any further as I will surely do my best to help.
So least there's the part number, but not sure how most other people would be able to order it other than call them up and ask for the part number directly. I still think that they should include a converter if they're not going to give an option to buy it directly along with the pen.
But yes I knew the pen wasn't going to come with a converter because of reviews I've seen on it, but I didn't know that all my spare converters weren't going to fit into the barrel of it unless it was a really skinny one like my Yiren or Jinhao 611 has, but my Yiren won't work with cartridges, so the converter must stay with it [the coiled wire inside the barrel prevents the bottom of the cartridges from fitting in]).
Still quite a smooth writer though.
