Ink Review 

Supplies Used:

Smear Test (Dry Time):

  • 15 seconds – Solidly between 10 and 20 seconds. This average speed won't cause any issues in most nib sizes.

Drip Test (Water Resistance):

  • Low – Some ink and a mildy legible line is left with the drips but the smear line is nearly gone. Be careful with the coffee cup! 


  • High – Asa-gao is a bright and vibrant blue with excellent saturation. Some sheen can be seen with heavy application on Tomoe River paper.

Ease of Cleaning:

  • Easy – We find the Iroshizuku line to be some of the easiest inks to clean. This darker coloration may take a second or two longer to get out of the pen but it's by no means difficult! 


  • Medium – Swabs one through three show nice shading and a clear gradient between each. Shading shows up better on more absorbent paper like the  Leuchtturm1917


  • High – Like most other Pilot inks the flow is generous and feels lovely on the page. Nothing out of control but definitely a wet ink.

 Packaging and Aesthetics:

  • This lovely 50ml glass bottle is very distinctive, and perfect for displaying your ink. This distinctive shape is instantly recognizable, and the clean label ties the look together. The opening is wide enough to fill most pens from.
