KWZ Blue Blacks

Let’s take a look at two KWZ blue black inks: IG Blue Black and Blue Black. You can find these inks for sale at most retailers including Vanness Pens.

Swabs:

Left to right: Blue Black and IG Blue Black.

Writing samples:

Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.

Dry Time: 40-50 seconds

Water Resistance: Medium

Feathering: None

Show through: Medium

Bleeding: None

Other properties: Both had low shading.

On Walmart Pen + Gear copy paper there was some feathering in every nib size and few dots of bleeding.

Comparison Swabs:

Blue Black is lighter than Bungubox 4B. IG Blue Black is darker than the rest of these inks.

Longer Writing:

I used Pilot Vanishing Points with a Taroko Enigma Notebook. Both had average flows.

Overall, I really like both of these inks. I prefer the color of the IG Blue Black over the regular Blue Black, but you can’t go wrong with either one.
