UMR-83 Refills for Gel Ink Ballpoint Pen, 0.38mm, Black Ink, 10-Pack, Sticky Notes Value Set

I hate throwing nice pens away because I can't get refills...or the refills cost more than buying the whole pen. When everyone is talking about recycle & reuse, why is it that pen refills are so hard to find or not cost effective? THIS one is available AND reasonably priced.

I've tried other refills for my favorite pens and they were very inconsistant and would stop flowing before reaching the bottom. I took a chance on these and I've been impressed with how consistant the flow is...which is the most important part. I'm 75% through the refill and it still is functioning perfect.

While it bears the same stamp as the UMR-87 I have been working with, when I tried to put this replacement into my uni-ball Impact 207, I found that it would not fit. This replacement part is too large.

Came as advertised. All refills have full ink. They make very clean and sharp lines. They do not bleed through very thin pages so I prefer these for note taking in my engineering classes over Pilot 0.38mm and Uni Jetstream 0.38mm.

Refills shipped quickly, was exactly as described and worked perfectly. Just a reminder, don't throw away the "spring" that is currently in your pen because you'll use it with your new refill.

I liked that it was easy to insert it into the pen. I would have liked a thinner point but this is very usable. Although I have many pens, I use this one exclusively at home because it is so smooth.

i dont understand why the UMR-85 is very smooth before, and now it is just like crap, very bad writing experience, and i spent 16 dollar for this crap. damn it!!!!!!

Ink is great. No skipping. Items fit into my pen (0.7) perfectly.
