Solid Daily Driver Pen
solid daily driver pen. smooth and consistent ink. i'm also liable to leave pens in my various kits for months at a time so i had to switch to capped pens. i purchased this 5-pack almost a year ago in March 2025 and the two pens I still haven't lost write as well as they did on day one.

Reliable for smooth clear lines
Great pens at a good price. Perfect for writing, journaling, art projects. Smooth and clean lines. Give them a minute to dry so they don't smudge.

Pens are great for fast sketchers
Great pens for sketching. They’re not stingy on ink while I’m drawing, so I can write fast.

Calidad
éstos como todos los uni, van muy bien. Distintos calibres para variar. Me gusta más que este el univall de luxe.. , pero está muy bien!

My go-to pens.
I’ve been buying these pens since the early 2000’s. They never fail. I don’t recommend using them on glossy surfaces as the ink will spear. Bonus feature, the tip is strong enough to cut tape to open boxes.

Le prix est beaucoup trop élevé pour ce que c'est
User
Great deal for price and pen
Excellent pens for 2 dollar, rollerball pens are good and with no pressure ink comes out and it’s high quality with a fine nib, great for people who don’t want to write with lots of pressure and good for artists
User
Best for pen and wash.
Watercolorists, this is one of the best waterproof pens for pen and wash.Draws fine and is absolutely the best choice.
