Round - 4000R Series
When people think of a fine art brush, they picture a round. The iconic, rounded shape is versatile, allowing artists to lay down washes, fills, and lines of all sizes. Rounds on the larger side can efficiently transform wide surface areas with fewer strokes. Those with finer points excel at delicate lines and intricate details. This brush is on a long handle.

Commonly used in landscape painting or when painting atop paint. This brush is on a long handle.

Great brushes
Nice flexibility and a great edge. I immediately used this set and nothing else to make a little painting and I love them! They’ll definitely be my go-to brushes.

My favorite brushes.
These are my favorite brushes. I'm an oil painter and these have a great spring to them. I like the long flats the best. Thanks Trekell .

Hi Branham, Thank you for your feedback! We are thrilled to know that the Opal Synthetic brushes are your favorite brushes! Thank you for your continuous support and for being apart of the Trekell family. Thank you, The Trekell Team

Damaged brush
The minute I started to paint with it I realized the barrel and handle are loose. Can I send this back and get a new one? This is the first time I have had any issue with your brushes.

Love Trekkel brushes!
I've never bought a Trekkel brush I didn't love.

Snappy
I do like these brushes - snappy but softer than genuine bristle, sort of a workhorse for me. It's now December 2022, and so far they are holding up pretty well despite my abuse! The ONE issue I have discovered is that the ferrules tend to loosen, more or less right out of the gate but after a use or two. Trekell, I sure wish that could be fixed. (And FTR they do NOT spend much time in solvent or water, just paint, until it's cleaning time.) Not sure what's up with that.

Awful brushes
These are the worst brushes I ever purchased. I threw my money away. Don’t do the same. Wish I had gotten the synthetic mongoose. Dang.
