Soak test update...

 

I haven't had a chance to scan the results yet, but a 15-20 minute soak in water, ammonia or bleach has no effect on the color or intensity of the ink. So, as stevo predicted, the Q-tip rub test was the same as the soak test. The only difference was the vigorous rub with the ammonia-soaked Q-tip barely lightened the color, the soak did nothing at all. I can post results later today if anyone really wants to see the test strips.

It was not well liked and it was expensive. I bet it didn't sell well. I tested it against the Noodlers Bad Blue Heron and Bad Belted Kingfisher and the PR ink was no where near as nice. It was tough. It'll be interesting to see if they replace it. The PR Invincibla Black has been released in a new formula at a lower price but I haven't seen a review yet.

      On my second trip to Japan in seven months, while the going is good

      Oh to have that translucent pink Prera! @migo984 has the Oeste series named after birds. There is a pink one, so I’m assuming Este is the same pen as Oeste.    Excellent haul. I have some Uniball One P pens. Do you like to use them? I like them enough, but don’t use them too much yet.    Do you or your wife use Travelers Notebooks? Seeing you were at Kyoto, I thought of them as there is a store there.

      It's not nearly so thick that I feel it comprises my fine-grained control, the way I feel about the Cross Peerless 125 or some of the high-end TACCIA Urushi pens with cigar-shaped bodies and 18K gold nibs. Why would you expect me or anyone else to make explicit mention of it, if it isn't a travesty or such a disappointment that an owner of the pen would want to bring it to the attention of his/her peers so that they could “learn from his/her mistake” without paying the price?

      Why nobody says that the section of Tuzu besides triangular shape is quite thick. Honestly it’s the thickest one among my many pens, other thick I own is Noodler’s Ahab. Because of that fat section I feel more control and my handwriting has improved. I can’t say it’s comfortable or uncomfortable, but needs a moment to accommodate. It’s funny because my school years are long over. Besides this pen had horrible F nib. Tines were perfectly aligned but it was so scratchy on left stroke that collecte

      My notes and advice on fountain pen cleaning

      By inkstainedruth · Posted

      @asota -- Yeah, I think I have a few rolls in my fridge that are probably 20-30 years old at this point (don't remember now if they are B&W or color film) and don't even really know where to get the film processed, once the drive through kiosks went away....  I just did a quick Google search and (in theory) there was a place the next town over from me -- but got a 404 error message when I tried to click on the link....  Ruth Morrisson aka inkstainedruth
