In reading this thread earlier I realise that I needed to "wear in" a Vulfix Travel Brush (bristle, no numbers - c/w travel tube) which I bought from Paul @ Connaught about three months ago...this evening I have had a practice lather using the dispensible Wilky Blue and I have to tell you, friends, that it produced a beard of Santa proportions. Perhaps the smaller and stubbier (and this brush is small and stubby) the brush then the more response comes from this much maligned soap?
Holiday in a few weeks so this brush will get some action in preparation.
