- Reviewed in the United States on March 4, 2025These Uni-ball gel pens are fantastic! The ink flows smoothly, creating bold, opaque white lines that stand out beautifully on dark paper and artwork. The broad tip glides effortlessly, making it perfect for writing, drawing, or adding highlights. Plus, the ink dries quickly and doesn’t smudge. A must-have for artists, calligraphy lovers, or anyone who needs a high-quality white gel pen
- Reviewed in the United States on February 8, 2018This review is made in comparison to the Sakura White Gelly Roll, which is what I’ve been using exclusively up until now.
PROS:
• Even and consistent ink flow.
• Very opaque.
• Rubber grip and thicker barrel makes it much more comfortable and ergonomic.
• Can go over lines and do multiple layers to make sections thicker.
CONS:
• Pen tip is much larger (1.0 mm) compared to what most people are used to on a Gelly Roll
• Distributes a lot of ink (takes some getting used to).
• Slightly longer drying time.
I was skeptical of the Signo making that much of a difference compared to the Gelly Roll but it surprised me. With both pens, I always do a little “warm-up” scribble before I go into an art piece — but with the Signo, I can rely on the ink flow to stay consistent and even until I’m done with it. If not, I can easily go back to areas that need touching up without ruining the ink I already laid down. With the Gelly Roll it would skip frequently and when I went over another area again, it would always scratch the ink already in the process of drying — this often turned a small touch up into a larger problem.
The Signo is also a lot more comfortable. Often times, my hand would cramp up with a Gelly Roll because of its skinny barrel. Especially since I would have to spend more time with it going over areas to make the lines more opaque or filling in areas the ink skipped. With a Signo, I usually only have to make one pass.
Yes, the Signo produces a much bolder line than a Gelly Roll — because of that it does release a lot of ink and needs a little longer drying time. It’ll also take a bit to get used to and familiar with so you can control it and know what to expect when you detail/write.
Overall the Signo is a great alternative to the Gelly Roll. It’s now my go-to pen, although I still plan to always keep at least one Gelly Roll pen nearby for times I need to do very small details.

- Reviewed in the United States on December 13, 2024I love these pens. I've been searching for a white ink ballpoint that's small enough to fill in the numbers on resin dice, and these work great. They're still a little big for the D20, but the ink flows smoothly and is easy to control, the white color is vibrant and bright. Super glad I grabbed these.
- Reviewed in the United States on April 16, 2025Excellent pen!! Great for artwork on black or other dark paper. This glides across the page. I'm hoping to find other colors!!
- Reviewed in the United States on January 10, 2025The pens are great! I was just a little sus about the packaging. There was no formal packaging other than the plastic bag. It made me wonder if it was previously used. There was also no ink tip cover.

- Reviewed in the United States on April 28, 2025These are GREAT ! Right out of the package they wrote smoothly, and there weren't any skipping in the lines.
I didn't have to do ANY priming, or other gyrations you often have to do, to get these type pens writhing smoothly.

5.0 out of 5 stars Usabilidad. Cubre sobre múltiples materiales.
Me llamó la atención que un producto como la tinta correctora viniera en formato bolígrafo. Esta marca, UNI BALL, es para mí una garantía. Pues utilizo los bolígrafos desde hace tiempo. Y me he hecho adepto por su calidad de escritura y trazo perfecto. Digo "tinta correctora" y no tinta blanca, que quizá fueran términos más precisos, porque utilizo estos bolígrafos para ese menester y no para dibujar, como mucha gente. Son comodísimos. Tinta blanca muy fluida y brillante. Cubre muy aceptablemente bien. Y no deja grumos ni pegotitos que abulten el papel. Pueden escribir incluso sobre materiales lisos y brillantes tales como el plástico de una tarjeta de crédito o el cartón brillante del envase de productos comerciales. No puedo valorar la durabilidad porque escribo esto minutos después de recibirlos. Pero sí la calidad de la tinta y el aspecto que deja al escribir. Seca casi instantáneamente. En segundos. Muy interesante. Llegaron tres bolígrafos en un sobre de cartón de Amazon. Muy satisfecho. Como casi todo lo que adquiero aquí. Será que Amazon permite ser muy selectivo y hay mucho donde elegir. En este caso, de nuevo, los UNI BALL SIGNO UM-153, son absolutamente top.

5.0 out of 5 stars Great for highlighting
These were highly recommended to me from a colouring group that I am in. I couldn’t wait for them to arrive and I wasn’t at all disappointed. They colour great on top of my alcohol based markers for highlighting areas. The pens are comfortable to hold and I’m pleased with their overall quality although they are my first set of white gel pens so I have no others to compare them to yet.

Mario PacchiarottiReviewed in Italy on June 19, 2019
5.0 out of 5 stars Perfette per le tecniche miste
Queste penne gel bianche possono avere molteplici utilizzi. Io le uso per piccole finiture su acquerello, quando non ho voglia di utilizzare il liquido di mascheratura o mi serve una particolare precisione, o quando la decisione di utilizzare del bianco arriva successivamente alla stesura del colore. Il gel è molto coprente, lascia una vera e propria patina percepibile al tatto (e questo può essere un vantaggio o uno svantaggio a seconda dei gusti e di cosa si vuole ottenere). Asciuga abbastanza lentamente e quindi va posto un minimo di attenzione dopo e durante l'utilizzo.
Il segno non è sottilissimo ma accettabile. Bisogna fare attenzione a dosare il tratto per non trovarsi con un eccesso. In generale comunque sono troppo comode e nel mio kit portabile c'è fissa una di queste penne.
Il prezzo del trio su Amazon varia molto, prima di acquistare verificate sempre che sia in linea con quello che le paghereste in un qualsiasi negozio fisico, o minore, per evitare fregature. Per ora non ho trovato difetti rilevanti.
