MiniatureModeler takes a look at the brushes from StyleX and gives you their thoughts on the subject.
From the review:
In surfing the internet one day, I ran across a review for StyleX Hobby brushes. The reviewer made some bold statements that these were a much more resilient synthetic fiber and he had not noticed any of the degradation that is so typical of this type. I was intrigued.
Fast forward to making contact with StyleX, I wanted to see for myself. Thanks to Jason at StyleX, I was provided many samples of their products to review over the coming weeks. I want to start off with brushes and post my findings.
