Let’s take a look at Kobe 66 Seishin Cobalt Blue Sky. You can find this ink for sale at most retailers including Vanness Pens.

The color:

Seishin Cobalt Blue Sky is a medium blue with a slight green undertone.

*For my swab cards I use a Col-o-ring by Skylab Letterpress, a medium Pilot Ishime and a Mabie Todd Swan.

Swabs:

In large swabs on Tomoe River paper the ink has some pretty pink sheen.

Writing samples:

• Leuchtturm A5

• Pen & Gear Paper from Walmart

Other properties: medium shading, high pink sheen, and no shimmer.

On 20 lb copy paper there is some feathering and bleeding in the larger nib sizes.

Longer writing:

I used a Montagrappa Elmo with a medium nib on a Taroko Enigma notebook. The ink had a wet, sticky flow.

Overall, this ink does have some issues due to its high sheen-long dry time and sticky flow, but I didn’t notice any smearing. Neither issue is sever enough for me not to use up the sample that I have, but I wouldn’t buy a full bottle of this ink.
