I LOVE these brushes....

I LOVE these brushes. I've tried a few different brands of waterbrushes, and these are definitely my favorite. The water comes out just right when you squeeze it, unlike some which will squeeze out too little or too much. It's also really easy to refill. And the shape is great because it won't roll off the table. The brush/bristles itself are also the best around. My regular watercolor brushes are pretty much obsolete now because of these Pentel Aquash brushes. The large size is my favorite, but if you're going to be doing extremely detailed work you might want to go for medium or fine.

These water brushes arrive...

These water brushes arrive by way of Japan and are quite ingenious. Traveling with a sketchbook, a small pan of cake watercolor and this brush means you are always primed for creativity.
Cake watercolor pans are recommended because the brush picks up color rather than soaks up color. And keeping this in mind it takes very small amounts of water to pick up sufficient medium. It also does away with a container for wash water because the brush is simply cleansed by wiping on a paper towel, napkin or blue jeans. One is cautioned not to squeeze out water to make broad washes for sky or landscape. This is rather a tool for working in close with details.
Designed originally for use with watercolor pencils, it excels in this application. Of great value to the artist is the ability of the brush material to snap back to a sharp point and to maintain this under prolonged use.
The brush of course has limitations but the trade-offs in convenience and availability in the field make up for many of them.

I love the Pentel Aquash...

I love the Pentel Aquash Waterbrush Pen - Large. The large would have to be my favorite out of the small and medium. It can pretty much do both small and mediums jobs in one. I really like the new look it has now. I bought one last year and it was great, but after a while it started leaking and the bush is stained from the paint. So that's when I got another one. I don't know why but this newer one feels different compared to my older one. the water comes out at a steady pace and not all over the place. The cap snaps on and feels like it wont fall of at anytime. The Pentel Aquash Waterbrush Pen - Large is a must buy for when your on the go or just at home. I know I cant live with out it.

The best picked up 5 of these =) They might not work good on traditional watercolor paper I use it on Bristol board for coloring not really traditional watercoloring the size of the brush head is equal to like a #5 or #6 brush but it remains sharp after it dries.
It releases water as you paint trace ammounts or if you squeeze it you can release drops of water at a time.

I've emptied the brush...

I've emptied the brush once of water, and now it's full of a nice medium grey ink.

With water, it works well with basically any ink or watercolor effect I tried. I didn't get super exhaustive, 10-15mL of water is just not that much. But if you've only ever used student grade or kid grade brushes, this is a huge upgrade. You can get wet in wet effects, wet brush effects, and some dry brush effects. I can't tell if there's a difference between this brush head and the Pentel Pocket Brush Pen, but they're very similar. Both allow very fine detail, and with both, I'm not good enough at having a light hand to get the finest detail (tho after about a year of practice, I'm definitely better than I was). Filled with ink, it's like a Pentel Pocket Brush Pen where you get to choose the ink color. The brush can run a touch dry with ink, and squeezing the barrel can get you quite intense ink lay down, but practice should make it easier. And there are a lot of situations where having a brush pen in an accent color can make pen and ink art easier.

I haven't used other water brushes, so I can't compare across brands.

a very good water brush, the first out of many that ive tried. it has four stars because after about a year of heavy use, it's starting to fray. i know that it will happen eventually, but i was hoping it would have lasted longer than a year.

Works great - feels good in the hand. The feed rate when squeezed seems equal for all sizes of this brush (have a medium too). I might like it a bit "juicier" but most people should find these quite controllable. Roughly equal to a size 6 or 7 watercolor round.
