Even with digital devices, you always will need a pen around
Great, simple pen, Does not bled through paper or journals. Good for checks, since it will not "wash". Much better price than the big-box office stores.

Simple pen, with amazing ink
Thank you customer service. I got the 0.5mm version & they were great! My immediate favorite & I have a lot of pens. I got a bad box of the 0.7mm ones & they were not so great. I got an old box that was obviously sitting around for a while. Customer service sent me a brand new box & they work beautifully!!! They write so smoothly. I use them to draw. Thank you!!!

Good Quality Pens
Good quality. Wanted a finer point but these’ll work.

A little thin to hold.
I like the quality of the line and the ink but the diameter is just a bit small to hold comfortably.

Great pen...tried many and always come back
I am always worried that uni-Ball is going to discontinue these pens. I have no idea how many boxes I have bought or even how long I have been using these - at least twenty years. I love the way they write, no bleed or even excess ink. My handwriting is sort of a unique combination of architecture script and a doctor Scribble, I write fast and unlike so many other pens I have tried the ink never pauses, runs out, or bleeds at stops. I forget to put the cap on, no worries...write just the same. Leave a cap off for days or weeks, one alcohol wipe and it’s like a brand new pen... I tried the micro (.5 mm) and many of the things I love about this pen disappeared...the .9 mm is too fat and messy. Like Goldilocks the .7 is just right. I have also tried all the new gel pens whether from sharpie, uni ball, Sanford, and pilot...none have provided the benefits of this pen - needless to say my sons have plenty of rejects to use at school. Writing is probably one of the most subjective things humans do...even more individual than personal fashion or eating. If you are unsatisfied with your current pen, I can only advise that you give this pen a chance.

A disappointment.
I love Uniball pens and Kuru toga pencils. I find the Uni ink is waterproof and I use it to draw pen and wash watercolor pictures. I recently purchased a box of Onyx .7mm pens for watercolor painting. The first three pens I tried skipped badly. The pens felt like the tip had a burr that dragged on watercolor paper. This is the first time i have had trouble with a uniball product. I will probably send them back but I don’t know where to get waterproof ink at this price point. I guess I will go back to India ink.

Muy buen producto y a un precio razonable. Es muy ligero y la tinta dura bastante en comparación de los pentel energel. Aún estoy usando el primer bolígrafo y este si no es muy consistente en cuanto a la tinta , veremos si solo es este bolígrafo. Compre otro paquete 0.5 mm en azul y adiferencia del anterior 0.7mm este es muy fluido y consistente en cuanto a la tinta.

Compré éstos porque tengo aún algunos de un paquete que compré hace muchos años en una tienda de autoservicio. A pesar de los años funcionan todavía pues tienen una excelente tinta. Quise comprar más de respaldo y probar si la calidad es aún la misma y comprobé que efectivamente, por el precio son excelentes y aún siguen manufacturándose en Japón.
