These Pentel Arts Aquash Water Brush pens are so useful when I travel. I carry a small art bag and sketchbook with me when I go places. I really enjoy carrying these along, because I can actually paint anywhere I want. I have painted outside in fields, at cafes, on my couch, in the car, on trains, and all over Europe when I backpacked. They were wonderful, never fell apart, and the water was easy to control. I really enjoy the aspect of the pen holding the water, because it eliminates the need to clean up cups of water, paper towels, and the other messes that traditional paint brushes leave behind. It is particularly excellent for blending gouache paint. Gouache is hard to blend, but the water flow in these pens is so consistent, that I almost always get an even gradient when blending with gouache paints. The only thing I would change about these water brushes is that the largest brush bristles always get pulled down by the cap. You have to very carefully place the lid on the large one, otherwise the bristles always get messed up. Other than that, this product is excellent. I fully intend to purchase more in the future. The handle is comfortable, and everything about these brushes feels so intuitive while working on my art projects. I would definitely recommend these to a friend. In fact, I have recommended them to a lot of people so far. The brush bristles do eventually become stained by darker paint colors, but that is inevitable with any paint brush after prolonged use. The price is remarkably affordable for the quality this product offers. I feel like I do more artwork when I am on-the-go than I ever have before I had these brushes. I am so thankful I jumped out of my comfort zone and decided to purchase these products. Pentel always delivers excellent quality, and once again, they did not disappoint! Five stars from a very happy customer!

I love Pentel Aquash waterbrushes. I use them in my art journals and when painting en plein air. They come to a sharp point and the water flows just right after you get them started the first time. This is the first time I've had a size small (good for fine work) or the flat one (good for blending, quick washes, and wide lines). The flat one even comes to a fine point and their lids are different colors so you can tell one from another. They are a value for the money and getting them in a pack of 4 saves you money.

I love the assortment of four brushes - these are great water brushes, the best I've used. Good water reservoir size, but the brush heads themselves really push the pigment around, allowing for good technique IMO. Will definitely purchase these again in the future.

I use this for stamped image coloring. I use stamping up ink mostly with these as well as using them to put down water for my water color pencils.Pros~~~~~~Easy to fillNo leaking thus fareasy to squeeze out more watercolors seem to come off easily (inks)Very nice to use with water color pencilsWorks great on the Ranger Craft Sheet (which just wipes clean) I put down some water to mix my water color pencilsEasy to control amount of water coming outNice different tip sizesGets into detailed area pretty easily if you have a steady handEasy to storeShipped quickly & packaged well.Was cheaper then buying at the craft store.Easy for kids to use as well.Cons~~~~~~If you are using the ink lid to pick up color, it can be very hard to get enough color. The colors seem to be very light-so if you want bold color better off going with water colored pencils then these brushes. However, you can use these to put down the water first then use the water color pencils.My View~~~~~~~~Overall I'm very happy with these brushes. They are fun to use & easy to control.Really love the 3 tip options.

I ordered these brushes as a way to more easily paint tattoo flash style paintings (instead of spit shading) and I was always curious how these pens actually work. They are easy to fill from the sink, but I think if you tried to fill these on the go you would need to bring some sort of squeeze bottle with a fine tip to fill these without making a mess. They do hold enough water that I only needed to fill it twice while doing a sheet of 9" x 12" flash and I think most of the water that I used was while I was cleaning the brush between colors.It's easy to clean the brush while your painting. All I did was keep a piece of paper towel handy and squeeze some extra water through the brush while touching it to the paper towel. This is also handy when you want a bit of a dryer brush. Swipe it on the paper towel a few times and you're ready to go. It doesn't hold onto colors or transfer and the only thing that stained it a little was red paint.I used these brushes with both traditional watercolor paint in a tube and with watercolor pencils and they work great with both. I do prefer the watercolor pencils though because it allows for more control.Don't squeeze the brush too hard because you will get a big droplet that comes out of the brush. As long as you avoid doing that, you won't have a problem with big blobs of water on your work. If you were to give this to a kid, their first instinct would probably be to squeeze the heck out of it, but you need to squeeze very lightly until you see the water travel through the reservoir into the tip of the pen.The cap fits nice and securely and you can actually store it on the end of the pen and stand it up right on the flat bottom of the cap.I ordered the pack of 3 and it gives a nice variety of sizes. I find myself using the smallest one the most.Overall, I'm very happy with these brush pens. Only time will tell how well they hold up, but so far so good.

These have quite changed my life. So great for sketching - take it anywhere and get painting in moments. Take a piece of kitchen towel with you too, or save your napkin, to easily clean your brush. You will never need a jam jar full of horrible brown muddy water to clean your brushes again.I just use this on big size.

The brushes work very well when used to moisten watercolours and then used as a brush. They work equally well for a large wash or for applying fine details. I use them both in the studio for quick studies and in the field as it eliminates having to carry another source of water. I also use them to for applying shades of grey by filling with water and adding a few drops of India ink. I have three different pens with different intensities for different shades.

After reading some previous reviews I purchased this brush. It has priced so useful when sketching and drawing outside. It's particularly useful when on holiday as it is small compact and easy to carry. The quality of the brush is good and one can get a decent quick wash od colour when needed. It also works well with plain water and a pallet of colours.
