Here is their web-site:

There is a description of their manufacture.
These brushes are not cut or clipped but in my opinion beautifully formed, at least the numbers I posted.
I like them much better than the Silver Brushes, which in my opinion are overrated.
There is a painting I did way back on unveiling's called "Alicia Rose" which I did completely with the aforementioned brushes. I would use few else, since quality and performance are paramount to me. The Kevrins are wonderful for faces as you can manipulate the stroke from the flat side to the thin edge quite beautifully. They wear like iron. I have gotten them both from NY Central and the Italian Art Store and have never had the problem you described. Very confusing.
But as they say different strokes for different folks. You have to find the brush that performs best for you. I have tried them all, even ordering brushes from Cornellisens in the UK.
