Onyx - Synthetic Squirrel - 6" Short Handle
DESCRIPTION
Designed with control in mind, Trekell’s Onyx brushes unite precision with unhampered flow, all without the fear of flare outs. These brushes come on a 6" short, black and silver-lacquered handles and nickel-plated brass ferrules. Not the qualities you expect from synthetic bristles, right? And yet, like Trekell’s other synthetic brushes, an Onyx mimics nature incredibly well. We bet you can’t tell that these weren’t once part of a squirrel. So, the only difference is price. So, watercolorists, why wait? An Onyx brush will soak up what you need and paint exactly what you want.

Supposedly named for its original use: painting ships' rigging. This brush is on a short handle.

Great Brush
Surprising amount of control and snap for a brush that holds a good amount of paint and water. It is marked 5/0 and is very close in size to the 10/0 that I bought with the set, wish I’d gone up a size or two. Still I am very happy with this brush.

About the quality
Excellent product i like the quality

AMAZING Synthetic Squirrel Brush!
I picked up several Onyx quill mops as I was both interested in trying the shape of the bristles as well as the paint load carrying capacity of the synthetic squirrel make. WOW. I don’t know why I’ve been so shy to work with quills! These brushes are fantastic! I usually work smaller and have mostly used round synthetic sable brushes to paint, and I’d always find my brush going dry when trying to apply wet washes of color. These quills give me precision AND carry a large load of water/pigment, so I’m able to cover the area I’m painting and then some with a single brush load, covering everything from big empty areas to tight corners that require a pointed tip. I’m a big fan of the Onyx for watercolors and highly recommend this brush! This was my first time experimenting with Trekell brushes and I’m not disappointed! If you’re curious about my work, find me on IG under @eggbunni — you can see the sort of paintings I create with Trekell brushes. :)


Fantastic Burshes
These brushes are wonderful! You can feel the professional quality after one stroke. They are quite soft. Which is great when laying down paint. But I have to get use to them I usually work with a firmer brush. But other than that I recommend these to any painter! You got to get you some!!!

Love these brushes
So far I am loving everything about them! I actually see improvement in my artwork. Thanks
