Don't hesitate, just buy this pen! Feels like a real brush and restores manhood.

This is the best brush pen I have come across so far.

I have tried out several after and before this one, and I must say, this really, to me, is the best. I think comparing it with felt-tip brush pens isn't necessary at this point, felt-tips just feel totally different than "hair" tips. The feeling of authenticity can only really be conveyed via 'hair' tip brush pens I think.

Recently, I bought the Pentel Standard Brush Pen (tsumi tip - a little thicker than the pocket brush pen) to have another hair/nylon tip to compare the pocket brush pen with. I wrote a little review on it as well. This one still remains my favourite.
Both drawings and writing kanji works smoothly and beautifully, the ink is rich and deeply black, it's waterproof (when I use a waterbrush on the writings, the ink would run and a slightly pink background colour would appear with the Standard Brush Pen, however with the Pocket Brush pen, nothing would happen apart from the thin paper rippling)

All in all, I absolutely recommend this brush pen. I'm sure it will make you happy.

Awesome pen,real Japanese style of broken brush line.l could not use it for some more rigid,fine,bold black comic-like drawing but for more expressive style it is just phenomenal!..l like the poetry of a hand movement it follows so beautifully,giving a hairy-thin line at the tip and that lovely,broken line when you freely increase the pressure from time to time.Feels like some sort of a Zen meditation,it really kinda dances in a hand.Best soft tipped brush pen l've used so far and l could hardly believe that it could be beaten out someday.

I really enjoy the spring and snap of this pen. Although the ink can be cumbersome under the "wait until it's dry" circumstance of adding watercolor, or running my hand across my image (lefty here), the lines I can get from this pen are always what I want. From hairline thin to thick, wet strokes.

I always carry this in my bag with my sketching items and the ink lines are gorgeous on a nice sketch paper.

I'll always own one of these until I'm pushing up daisies. They're just worth it.

I absolutely love this pen. I've been using it for years and years and it's always served me well. It springs back well, and takes all my abuse. It's worth it- it will be a very faithful companion.

I specifically went looking for a pocket brush pen that could fit inside my smaller watercolor materials case. I usually prefer the pentel pigment ink brush pen, for its deep black and absolute waterproof-ness, but it's much too long to fit in there. So I went looking and found this.

The images and even other reviews said it was waterproof. It's not. Even leaving it to dry for a good half hour still resulted in it developing pretty much a dark grey wash effect when quickly gone over with a water brush. I tried all my different papers in a full on gauntlet of trials, "maybe it was just my first paper not working well with it", I thought. But same thing, none of them resulted in the crisp whiteness shown in the example picture.

The entire reason I bought this was for it supposively working with water, so now with that option out I've got one extra pen I will need to find some other use for.

Excellent! Has a very black ink, not washed-out or grey. The brush is springy yet soft enough to be bent down into a fan of bristles on the page if you so desire. Has a wet flow when moving slowly, and a charismatic, dry-bristle look if you go faster than the ink has time to refill the tip. Easy to refill as well. I recommend storing this pen on its side - it can leak into the cap if stored brush-down, and will take time to start if stored brush-up.

I used a Pentel pocket brush pen to ink my comics for years and years. My brush finally frayed after 2 years of heavy use (about 120 pages of comics). I ordered a replacement pen and to my dismay, it frayed within 6 pages! I figured I might have gotten a bad batch, ordered a second and had the same problem. I bought a third from Utrecht Art and ran into the same problem.

It's unfortunate that the quality has declined, as this was my go-to pen for a long time. Now I'm on a hunt for another brush pen. If you get a good one, though - oh man is this pen amazing.

There's a reason so many rave about this brush pen. Inexpensive with replaceable cartridges, it does a fine job in various applications one use's a brush pen for, with a tip that's very responsive in line sizing. Nice deep black too. Nice balance and very light in hand.

This pen is absolutely wonderful! A sythetic hair brush tip with good spring, it gives graceful, dramatic line variation from tiny hair strokes to bold flourishes. I've never had problems with the ink overflowing or drying out; I've even left the pen unused for weeks at a time and it's still ready to go the instant I pick it up again. All this, and the ink, a nice rich black, is waterproof. I still want to explore other brush pens too, but this is my favorite drawing tool.
