It's ok
I purchased these for the Charcoal bristle brushes, I received the package, there are white bristle brushes and Charcoal bristle brushes in the package, they all have different letters but they don't tell you if the letters stand for the different softness levels of the brushes or what they represent. The brushes loose their bristles after about the first 10 brushes so they're definitely disposable. I am keeping them for guests to use but not what I was hoping for.
