great bruhes
i love them-- they work great when applying layers of wet paint on top of dry or wet paint

Brush review
Maintains an accurate chisel shape, doesn't shed, tolerates abuse like a pro. What more can you ask? Do wish that use of bristle bucks was a bit more suited to my simple mind...you know, like a "wanna use your B/B's ?" option-box at check out.

Best Ever Brush.
Have been painting almost forty years. Your Opal brush is wonderful. I will purchase no other from here on out. Since I'm 88, that might not be long though. Smile. Chaz

Outstanding Brushes for Oil
These brushes hod their edge. They have the perfect amount of spring to meet my needs, and surprisingly, I find it easier to clean these brushes too. I now use these as my go-to brushes!

Soft and strong!
These are a little softer than the hog brushes from what I can tell. Hold their shape beautifully. Very crisp! Love them!

Best Synthetic Oil Painting Brush EVER
I have been painting for 60 years in oils and have tried every kind of hog bristle and many synthetic brushes of numerous brands. I'm not particularly hard on my brushes and I do understand they will not last forever or even for very long, no matter how well you take care of them. Canvas just naturally wears down the fibers over time. In my first Trekell order a couple of months ago I chose a few Trekell Hog Bristle and a few Opals (all long flats). I had to finish a finicky detailed commission over the holidays and ended up using the Opal #0 and #4 almost exclusively and while the #2 Hog started to splay and fray, the Opals were troopers. Still are. Opals are the very best synthetic brush I've ever tried. They have just the right texture to the fibers that mimic hog bristles far better than any other oil painting synthetic which tend to be too soft, sable-like and wimp out. I find Opals extremely resilient and long lasting and just got my second order of several more sizes and styles. I do love the long flat, though. It gave me great control in the most detailed areas but allowed wonderful loose brushstrokes when applicable. That said, Trekell Hog Bristles are also very good. Right up there with some of the best brands. But I am now a true convert to Trekell's Opal line. Chris Witkowski
