Buzz Presto Series 450 Acrylic Brushes

I have had a lot of trouble getting these brushes to work for me. They tend to push the paint around instead of depositing it, which looks really terrible with student-grade paints that aren't super-pigmented. They barely flex even when I apply substantial pressure which makes it difficult to paint in clean lines (I am using them to paint pretty basic shapes and patterns). I am new to acrylic painting but I suspect that these brushes might work better for a very thick, heavy-body paint that is very pigmented...but these brushes are intended for beginners, and beginners are unlikely to be using paints that are higher in quality (and therefore, more pigments) than student-grade ones. I think I will try the Bravura line next, as those brushes are described as having soft bristles.

great brush, holds paint nicely
I have several of the Buzz Presto Brushes Series which have all been awesome.
