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

The Uni-Ball Signo line is always great and this has become my favorite refill for the Big Idea PHX-Pen. This refill is a great combination of a very fine line with a smooth feel that also gives some feedback from the paper. If you like refills that are smooth without being too smooth... I hope that makes sense... this might be it.

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.

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.

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.

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.

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

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.
