三菱鉛筆 Mitsubishi Pencil Uni-Ball One UMNS38.2 Gel Ballpoint Pens, 0.01 inches (0.38 mm), Yellow, 10 Pieces

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

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

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.

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

Value for money. I ve always loved this pen, got these for much less than at the bookstore
