I bought four different sizes of round brushes. All of them are bent at the very tip so I cannot get a fine line with any of the brushes. One of them started to crack right away at the handle, under the metal part for no reason. My instructor returned one of them for me. But again, even the small round brushes are not really usable because of the bent tips.In the picture is a size 3 round brush. If you look real closely the very tips of the brush is bent. It's very slight so I didn't think much of it BUT once you start painting you can only get a very dull line, especially on a brush that small its just annoying. To remedy this I bought some cheap nylon brushes from Daiso and they can actually make a tip.

I was given a set of Pabeo paints two years ago and it included one Winsor & Newton - Cotman paintbrush. I used that brush for almost every watercolor I have done since. I finally looked online at dickblick.com and saw that they carried this brand and ordered almost every size that they have of round brushes. I am so pleased withmy purchase and cannot wait to get started!These are fantastic brushes!#sweepstakes

This brush seems to just float across the paper and spreads the paint and water beautifully. Even with the large brush head, the tip is very fine and holds well so I can get a very precise line as well as a large wash of color. #blicksweepstakes

These synthetic brushes are great. They apply colors evenly and pretty much do what the more expensive natural hair brushes do. We like them. This set completed my rack of brushes so now I have all the sizes I need.
I use these brushes to paint stamped images for greeting cards. I love that the round brushes keep their point, and they last forever even with frequent use. The bristles are soft and don't damage the lightweight Arches watercolor paper that I often use. Unfortunately, the most recent 6 round I received didn't have the plastic cap, which I like to keep to protect the bristles when not in use. I keep my brushes in a plastic box and they rattle around during transport. Otherwise, I love these brushes for their competitive price point and performance. I highly recommend, but I think next time I'll purchase at the store instead of online to make sure I save the cap. Great product!
The filbert brush works and maneuvers design effortlessly. It has the perfect combination of firm and soft bristles and absorbs water consistently and helps paint with the desired amount of pressure. #sweepstakes
I'd purchased several of these brushes through the website and after a week or less I noticed that the paint on the handle was peeling off in large chunks. At first I thought it was merely a cosmetic issue and decided to just deal with it since the actual brush worked very well. However, I've used them for several months and now more paint is coming off the handle and falling into my artwork while it is still wet. It's incredibly annoying to pick out chunks of paint from the handle out of my art. Very dissapointed in the quality of them because of this. I expected better quality control in a product from a company like Winsor and Newton.
My brushes where 30 yr old. I did not want to invest huge amounts of money in to new brushes. These are great brushes for the expense. I think they perform better than other student grade brushes I have bought. They have spring and load up with color well.
I bought the Set E, Set of 7 a while back when I first wanted to learn watercolor painting. I dug them out of my art box in the closet again recently when I wanted to pick it back up. These brushes are fine. Excluding the rigger (I really don't like the rigger in this set) they have lots of snap, and are soft but not floppy. They hold a decent amount of paint and water, but it's nothing to write home about. While I won't toss them, and I'm using them for gouache now, I won't replace them when the time comes. There are just so many better brushes on the market, and while it's true that they cost a little more, even just $15-20 gets you a round 6 brush several times better than this one.
Winsor & Newton products never fail to come through for me. The One Stroke Brush is a great addition to my brush set. I do watercolors and this brush is great for waking up my colors as well as being perfect for a more structured wash. The other brushes I have from Winsor & Newton have served me well and have lasted quite a long time.
