"I have been using Hamilton Perfection brushes for many years ever since starting in the trade. I have no problem recommending these brushes to any expert tradesman looking a for a extremely good quality brush which will last a very long time compared to other brushes.
They handle very well, they hold paint well, the bristles do not part when handling fine lines and edges, giving a smooth, clean edge when applying your paint. One of their finest qualities is that they are a full bristle brush, having bristles all the way through the brush and not just a few around an interior block like cheap brushes.
I would not recommend these brushes to anyone who does not know how to clean and store a brush properly, for continued good use proper cleaning and care is recommended, for the brushes sake as neglect will damage the brush and you will loose its potential to serve you well."
