Uni-ball Gel Impact UM-153 White [Pack of 3] Broad 1.0mm Rollerball

I bought these pens to write addresses on red envelopes for Christmas. They did a great job, the ink was opaque. I also used it to write messages on some Christmas cards that had a dark blue background. FYI, I bought what appeared to be the same Uni-ball UM 153 model white pens from a Japanese seller here on Amazon a few years back and they were horrible, skipping, and the ink was light. Maybe they were old or knock-offs? My latest purchase pens are good quality.

If you are looking for a white pen to add highlights over your colored pencils, this is the best pen for the job. With a single pass, this pen will glide on a bright, smooth line of white on pencil drawings. I tested it over both burnished and unburnished Prismacolor and Polychromos pencils, with excellent results. Great for adding whiskers, fur, sparkles, and other bright highlights to your art work.

This is an amazing white gel pen , better than the most known brand( gelly roll).I try it on black paper and it did a lot better than the other brand, it started skipping a little because I guess I pass it to many times in the same spot. Still is looking wonderful, I recommend this gel pen .

Works great as advertised, but not for what I wanted.The ink is thick and truly opaque. It shows up well on black and dark colored paper. The reservoir is much larger than the cheap chinese made gel pens found elsewhere. Overall, a well made writing instrument.But... I was looking for something to cover up the lines and numbers of my color-by-number books so that they would not show through the lighter colors. This covered up the numbers all right, but it would not take ink from a fineliner and a colored pencil just scraped it right off.But it does what it was intended to do very well.

I needed a new brand of opaque white pens for my drawings and found these, needless to say I'm very happy with my choice. It covers copic very well and is great for clean up, too, and application is smooth and not scratchy at all. Pens shipped and arrived in about two weeks, and the ink was perfect and not dried out at all. Very nice quality, especially for the price.

I love these pens I opened them and tried them out the minute I got them, they write smooth and they write great over colored pencil, thats mainly what I bought them for so I can put some highlights over my drawings. and they work fine they do smudge though (obviously) if you don't let them dry and you do sometimes have to go over the white ink a couple of times to get the right amount of ink you want but those are only little things these are awesome pens!

I was a Gelly Roll fan, but I finally broke down and tried these. Now I prefer them over Gelly Roll. The ink is more opaque and more saturated. I love these and would highly recommend them!

I bought these to use with coloring books and in general art. I just want them to add accents since I tend to forget (or mess up) and end up without intended highlights. I've done a few quick tests and they've colored well over colored pencil (even after using a blender to make the surface glossy), watercolor, and markers. The ink flows very well and makes it easy to make small stippled dots of white, which is something not all gel pens can accomplish. I'm pleased with this purchase, though I don't think I need all 3 pens and will probably be giving one to a friend who also colors. (Would be nice if these were sold in a 1 or 2 pack for a similar price point.)
