NOT 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.

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.
