Sailor Jentle Chu-shu, aka Mid Autumn, is another one of those inks I’ve had in my drawer for a long time but never spent much time with. I purchased my bottle on Amazon a few years ago, shortly after I discovered fountain pens. Since then, this ink has switched from the squat 50ml bottle I have to the square 20ml bottle. Amazon still has the 50ml bottle, but most retailers have sold out of them and switched over to the smaller bottle.
Chu-shu is a dark grey that strongly leans toward purple.
In large swabs the ink looks more purple than grey.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 20 seconds
Water resistance: Medium-some of the ink washed away, but you might still be able to read it.
Feathering: Low-there was a little bit of feathering on Leuchtturm paper.
Show through: Medium
On Staples 24 lb copy paper the ink feathered and bled in all nib sizes.
I used a Pilot Custom 823 in Smoke with a broad nib on Tomoe River paper. The ink had a wet flow.
Overall, I really enjoy this ink. I like the purple tone more than I thought I would, it has a nice wet flow and the little bit of shading is a nice bonus. Now that I’ve spent some time with it, I will reach for it more often.
