Buy IMMEDIATELY!
This pen, by far is the best white pen out there. As an art student we write on black card frequently. This pens flow is smooth and consistent and there is no streaks! Its brilliant, and its not even expensive! I have found that Japanese pens, especially Mitsubishi are superior.

Very good value for money white ink pen.
Very happy with this pen, which did exactly what I wanted it to. Good quality of the ink itself, enabling me to both correct a cartridge pen sketch and act as a stylistic tool for a pop art piece (where I wanted to blend felt tips into a pseudo-Ben Day Dot pattern). Worked very well with the felt tip pens; my words of caution would be1) To let it dry & don't try to do too much with it all at once (you'll have to keep a tissue nearby to keep the nib clean but for me that is no bother at all).2) Be realistic about what you can achieve with it. It's not a correction fluid, though it can act like one if you use it cautiously. It can certainly cover up light pencil marks but see point 3 if you're trying to go over anything heavier.3) Test it out beforehand! And then test it some more.Overall, a very good value for money white ink pen. I'm impressed & I'll be buying more of these for my art projects.

Great White Pen
I've been look for a decent white pen to add to my stationery collection for a while and now I can confidently say I have one and I would recommend it to other people that are in need of a white penPros:- When used on top of other stationery items the pen produces a true white colour- The design of the pen is very nice and easy to hold- Less expensive than other white pens- Smooth when using itCons:- When using it on top of markers that I consistently use, the ink goes milky doesn't retain its whiteness

Great white gel pen
I have tried many white gel pens and this is the only one that has worked for me.I use this with drawing and painting, the quality is great but a bit much for a white gel pen so not really value for money.It is very easy to use compared to the ones I have tried, the ink comes out with good speed and it won't randomly stop working or have to push down multiple times for the ink to come out.Great quality, great pen thank you

Great quality
The best white gel pen I’ve found, nice opaque colour ideal for covering black lines and adding small details.

BEST white pens I have ever bought
Not only are these very cheap, they are AMAZING quality. They have lasted so long and the ink is amazingly saturated. I have used white pens before and they are normally dull in colour or dont give off that much. these pens were the opposite. The only thing I have to say is to wait for them to dry. I have turned the page automatically after writing and it transfers onto the other, but I will not take a star away because that is no fault of my own. If you are looking for a white pen that lasts long, is easy to hold, very cheap and does the job, you have it here.

The pen runs out quickly
At first the pen wrote beautifully on black card. After using it a couple times I found the ink just wasn't flowing as nicely. I've tried a few thing to fix this (after researching on Google) but nothing seemed to work. This does now mean I have to go over it a few times to get it to be full white ink.That being said, if you only need it as a one off thing, or if you're happy with going over it a few times, it's perfect. If you want a long term pen I'd probably consider a different brand.

Excellent white pen.
These get a lot of use in my artwork and I love them.I have tried all sorts of white pens trying to find the one that works for me, and this is it. It flows easily (give the nib a gentle wipe if it starts to clog or feels like it is drying out), lasts well and doesn't fade.It is fine enough for quite a bit of detail and perfect for highlights in mixed media work.It might not be ideal for everyone, but it is certainly worth a try.

Amazing colour
Works great!

黒マステとの組み合わせが好きです。
黒のマスキングテープにこちらを使って、収納場所ごとに貼っています。書いた直後は落ちやすいですが、少し乾けば問題なく用途に使えています。モノトーンでしっくりきてます!
User
Excelente calidad
Excelente calidad en la tinta, sale fluido, constante, suave y cubre bien. Lo volvería a comprar cuando me acabe con todos (sobre todo por el buen precio en qué lo adquiri).

Uni-ball bolígrafo tinta blanco
Muy buenos, te salvan el día en muchos dibujos. Si son a lápiz, grafito o color, es recomendable dejar que seque (como en el tipex) y pasar el lápiz suavemente por encima si no quieres que quede blanco en contraste con el dibujo.
User
Definitely my preferred white pen for illustration.
This pen is a good addition to any illustrator's arsenal. The pigment flows well and the drying time is optimal. Compared to my other gel pens this is the one I prefer. Perfect for accents and corrections on ink illustrations. A definite must-have.
