Uni Signo RT1 Gel Ballpoint Pen Black Ink Refills, 0.38mm, Set of 4

Arrived in good shape, does a good job

The 0.35 signo pens are my favorite pens. They are ultra fine and write smooth; ink is quick drying so I don't have smudges on my hands after taking notes. Every now and then instead of buying a whole new box, I buy refills and convince myself it's more environmentally "friendly" because it is not a more cost-effective option than buying a whole new box. But, each refill comes individually wrapped in plastic. Would be worth it if switching from a different size. As far as writing quality, would say there is very few pens that compare so if this is a pen you are preferential to, it really is new or refill.

I'm glad they make these refills. My handwriting is small so I prefer 0.38 and 0.28 pens when I write. These refills were the right fit for my 0.38 pen. It takes me several months to go through all 4 of these refills (but it really depends on how much I write too). I love the way the ink flows and how nice it looks on paper. I notice the difference in my handwriting when I write with these vs. writing with a generic ball pen. I highly recommend these to anyone who has smaller than average handwriting.

This refill writes like a dream. It's not scratchy at all compared to the 0.38 pilot g2s!

The pen is very smooth and it works for long time. I will rate 5 out of 5.

Really like these refills. Smooth ink flow and the ink dries very well. Good standard size of refill that fits a majority of ink pens.

I love this pen! It doesn’t smear or run! Very comfortable. I use it everyday at work and it is very precise!

Work perfectly
