Uni-BallSigno DX UMR-1 Refill for UM-151 Ultra-FINE LINE-12 Pcs-0.38mm Ball(Black) / Attached with Dbmier A750 Mini Notebook

I like to have refills so I don't have one-use pens. And I love these pens, so refills will extend their life. Easy to switch out, too.

These Signo refills are exactly what I was looking for. I bought them for use in the Ti Arto pen and they are outstanding. The refills write very well. Good flow and reliable. I definitely recommend them to anyone needing to refill a 0.38mm DX pen or to use in an EDC pen that accepts other refills.

Excellent refills for my favorite pens, delivered quickly for a good price. I love that their 0.38 gel tip is protected with a tiny ball inside the sealed plastic wrapper. They rarely blot or fail to write smoothly & clearly. This is my 2nd order, as I don’t want to do without!But though I've ordered them twice, I have no idea about and have never seen any attached mini notebook. That's something that ought to be changed if it's not going to be included.

Exactly what we were looking for

I was lead to believe that these refills were the right ones for the Uniball Signo 207 pens; but they are not -- the cartridge body is too long and the point is the wrong length to allow the clicking mechanism to operate. I'll be returning these for a refund or exchange.

Not for the pen that i thought it would work for. I have these pens: http://www.amazon.com/gp/product/B00Y1TXDO6?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s00 and this was not the right size. Probably my fault. Easy to return though.

my favorite pen for many years now. smooth fine point gel. these refills are great.

only if you prefer 0.38 nib or smaller. This pen is fantastic.

These pens have been my favorite since 2000. I like fine point pens though. Not throwing away the body of the pen is good. Saves waste. And there was one free extra refill taped on the box with mine. Consider me a highly satisfied customer.

Very good
