Vibrant smooth colors that i've written with until the ink has run out

It's smooth, dries fast, and color is great

Great quality and color.

good pens, bright colors

I like that these come in good staple colors, although I wish it was a six or ten pack (in ultra fine point) with more different colors.

Great pens with very solid colors that dont bleed through pages

Rarely, have I seen the local office supply stores carry multiple 0.38 colors of the G2 which is why I was pleased to find out that Amazon carries a wonderful pack of G2's in my favorite colors at a good price

Love Pilot pen and especially the ultra fine multi color pens

I like the colors it makes it easy to do my book keeping in order

these do not bleed like older wet designs have--fast drying-these smear very, very little (red and purple tends to smear more than the other colors, for whatever reason FYI)--durable ink-this ink holds up better over time than older generation gel/rollerballs have and resists fading from UV light super well--colors-blue, black, green, and red all use colors that are easy on the eyes, give good contrast, and aren’t ugly

Really nice ink flow, solid lines & color, comfortable grip

The 0.38 gel pen is ideal, because you have the fine detail of a pencil or ballpoint pen with the rich color of gel ink

but if your one that enjoys coloring a lot this is the pen for you

The green color in particular is awesome

The color is vibrant and pigmented

I recently bought expensive pens that were .5 and multi-colored and these by far work much better and last longer!

I have been thoroughly happy with these pens: great color, great line (important to me for tight margin annotation), good (but not perfect) clog resistance, good (but not instant) drying time, and great resistance to paper bleeding (which is super important to me for textbook writing).
