## Description

This gel ink ballpoint pen uses new technology bead pack pigments to write darker text and proven to be memorable. "Notebook, crisp and crisp. uni-ball one 1: Black is darker and the colors are more vibrant, and the black color is darker than the general gel ink that can be easily remembered and clearly written letters.

Review: NOT 10 pieces - The listing is for 10 pieces but I received 1 only. For the price, this is a rip off.
Review: 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.
