Mitsubishi Pencil Uni-Ball One Gel Ballpoint Pen, 0.38, Green, 10 Pens Hako UMNS38.6

Love these refilled they are an excellent value for your dollar and fit perfectly in my uniball ball point pen. I love that they are .38 mm. I only wish they held more ink. I use them for EVERYTHING and do a lot of Bible study, sermon notes, and other writings. The ink flow is amazing the the quality and durability are great. I think of 2-3 purchases I had issues with one of them. All others have worked fine. These are my go to pen refills. I love the design and know that they fit my pens. If you love writing with a great pen and like very fine tips these are the best

Best refills around. Amazing price point for the amount you get. Doesn't smear. Perfect for TRP or Sanzen paper. Last a good while. Easy to switch out in the pens. No scratching. I will always buy these, especially in 0.38. writes so smooth! I could literally fill an entire store with the amount of pens I own and these are some of my absolute FAVORITE.

I love how effortlessly these pens write. They don't smudge and the green is so dark that to an unsuspecting eye just looks black. Can be used for checks or anything else you want. Super comfortable in the hand as well. I keep one in each car and all over the house because I won't use any other pen if I don't have too. I will buy again!

These are great! Love saving a bit of waste by purchasing refills rather than all new pens

Actually, I ordered One P on previous order and I took the refill out and put it in G2. EXCELLENT RESULTS! Great for small fonts writing. Wet hand test passed. Rubbing alcohol test passed. Moreover, I ordered another 10x 0.38 (this order) and 20x 0.5 (next order) to "upgrade" ALL gen pens due to exceptional writing experience with One refill (much better than 207 and 207+). Smooth and no "cutoff" No "ghosting" on back of the page (common problem with log book writing). Get this refill if you're not happy with gen pen you use (hint: G2)

Just what I need for my pen. Fits great and the ink is real smooth. Nice to have since I write plenty with the .38 pen.

Good pens from uniball. But the .3 might be too thin for my writing style in the field, one roller already stopped working. Otherwise the pens wrote smoothly while they still worked. Love the different colors

Very great value for money compared to other places that sell these refills. My only complaint with Uniball One Gel refill is that I wish there was more ink in each refill so that the pen can last longer. As someone who writes a lot for school, I find myself going through each refill extremely fast. Fortunately, the writing experience makes up for it.

replacement ink for uniball one P works great and exactly as described

Smooth writing.

The listing is for 10 pieces but I received 1 only. For the price, this is a rip off.

I am a huge uniball fan, always have been. When looking for a pen, I wanted something robust that would hold in the button sleeve of my shirt. This does this all day long. I sell cars and walk the lot and never lose my pen. I'm sad I can no longer find the 0.5 mm, but these still write nice. Other than my carbon fiber signing pen, this is the only pen you will ever need, and that I ever use.
