SAKURA Gelly Roll Gel Pens - Medium Tip Ink Pens for Journaling, Art, or Drawing - Classic White Ink - All Are Tip Size Medium 08-6 Pack

I used the pens to write in my black journal! Worked well, the writing was smooth and didn’t really smudge (unless you wiped it literally right after you wrote). I wrote a lot so I would often have to buy a new pack of pens every 3-4 months. I like this brand because of how easy it is to write. It flowed nicely too. Would buy again!

A decent pen for going over dry watercolor pieces, dark paper, or anywhere you need opaque white that does not immediately darken.

GREAT ink flow and ink quality! Buy the BLACK paper post-it pads with these pens. I love the white ink on black paper--I prefer writing this like. These pens write really smooth and the ink flows evenly. The tip of the pen can build up with white residue but just roll the pen a little and it's gone. Parents who want to get their kids interested in writing, give them this pen and the black sheet lined papers (Pacon--not pitching this product, it's just the only one available on Amazon) and let them go. [I'm wondering if the black paper is less harmful to the environment since there is no bleaching involved in the paper making process.] PLEASE SOMEONE MAKE ALL BLACK SHEET--no lines--JOURNAL BOOKS!For me, I can go through the ink of a pen in about one-two weeks; I write a lot with the white on black. My only issue with pens of any kind is the used pens: they should be recycled and I am more than willing to save used pens and ship them back to the manufacturer and let them refill my used pens and ship them back to me to reuse: The barrel, nip, pen cap and end can be reused; all the manufacturer have to do is either replace or refill the ink reservoir of my pens--OR, manufacturer can provide the ink reservoir and I'll pop it in. Billions of people around the world use pens--billions are thrown out everyday!

Continue to flow years after purchase!!!! YAY!!!!As with many gel-pens, these start slow at times, and have a little build-up of of ink around the ball of the ball point---but nothing unexpected with gel pens. When using after it's been a while (or in the middle of a project, as needed) I'll simply roll the pen a touch on my open palm (probably could do this on the sole of a shoe or something---anything with a bit of a grip; I just use my hand because it's simple) to get rid of that initial glob build up, and build-up during a project.Four stars because the pen tends to dispense the ink somewhat unevenly (thus writing on my palm).That being said...the pens last many years unused in storage---unlike many many gel pens. So I'm very happy with that!I use these pens as a cover-up for misplaced strokes in my India-inked artwork. The ink is opaque enough that it works perfectly. It takes me a couple of layers to complete the cover-up. I'm happy because this ink behaves much like paint, in that I can write one layer, let it dry, then add another layer on top of the dried layer. (Always make sure the India ink has dried first!)(I always do this as the last step in my artwork, since writing with black ink on the top of the gel pen may have unexpected results. In a pinch, however, I will use a fine-line Sharpie to go over the white gel pen. [ALWAYS make sure the gel pen is dry before writing over it with a Sharpie---or goodbye Sharpie! lol])

I am a professional illustrator and definitely recommend these pens. Although I render primarily in Photoshop and Illustrator, I am constantly sketching in toned sketchbooks and have found these pens work incredibly well for bright highlights. I also have done a few children's books in watercolor, and these gelly roll pens do a great job of laying a final highlight over other marks. They are definitely opaque enough. The only medium I have found they don't really work well with is prismacolor markers. Even when I would let the marker dry for a while, the white still seemed a little dull over the top of it.I guess the only negative thing I have to say about these pens is that occasionally they get a little gummy and i have to wipe the tip off with a paper towel, but honestly for the wonderful line quality and opacity that I typically get, that is only a minor complaint.I have used so many white pens and pencils and in the end find that my number one choice is the coveted gelly roll pen... So if you like strong, bright white lines to highlight and accentuate your drawings, this is the pen that I recommend.

Man, why can't these be sold EVERYWHERE?! I have ink pens in all kinds of colors, yet I never considered have ink that wrote in white. It's like using White-Out to write with, but you don't have to keep dipping the tip, although you will occasionally have to wipe the tip to keep the flow. The barrel is comfortable to hold, not premium, but for the price, you can't beat it. So far, I've written on construction paper, as well as typing paper printed with color, and like others have already stated, the ink writes silky smooth. Honestly, it makes me not want to use any other ink, of course the only caveat being the ink is white and will not show up except on colored paper. Still, if you're like me, you'll find the correct paper to write on simply because it feels good and it looks that good.

I bought these to use as accents on a darker painted canvas. Though I preferred the bold tip pens for my outlining, the med point were good for other scribbles and lines.

Used on my cricut explore air 2. Worked great but it does take a moment to realize where the pen sits to prevent streaking. Great product.
