uni-Ball UMR-10 0.1mm Gel Pen Refill | Usable for UM-153S | Blue Ink, Pack of 12

Used this in civil services exam (Mains). Very smooth for fast speed, especially in Ethics paper. But you need to allow it a few seconds to dry, otherwise it smudges.

First, these refills were made in Japan. Second, they are NOT 0.01 mm as given in the title and description by the seller. That would be an ultrafine thinness. Instead, they are 1.0 mm. I hesitated ordering the item, but took a risk, and I was rewarded by a thick, smooth-flowing ink. Wanted a refill for the Japanese UNI-BALL UNSGP153SBK3 Signo Gel, and am extremely happy with the product. I hope the seller will change the description. It is a pleasure to write with this refill. I'm glad I don't have to throw away the old pen. I hope the ink in the remaining 11 refills do not dry up by the time I get to use them--that is the only concern I have--though I don't expect that to happen because each of them comes in a tightly sealed plastic pouch, and have a protective nub on their nib ends.

This is Just right for Fast,Smooth & Impactful Writes.Japanese Uniball never disappoint.Also, it's good for any hand conditions.Although they must give flexible options for refill like 3/6/10/12 to mk it more feasible.

They are superb. The catalog mentions incorrectly 0.1mm, it's actually 1.0mm.Only downside is that they are depleted within 3-4 days, and the refills are a bit expensive than ordinary ones. 6X expensive but definitely worth its while :)

Good flowing ink...

Very smooth gel pen refills, now I can't think any other pen to replace this very good, but only one challenge refill finish very early

The thickness of point mentioned is incorrect .Actually it should be 1.0mm but mentioned 0.1 mm

Good items worth purchasing
