I've the superb SV badger brush which is the same size as Chubby 3 but not as dense. Ì follow SV guidance when loading hard soaps. Its almost fool proof. I soak the brush for 3 to 10 minutes and cover the soap with a thin layer of warm water. Gently squeeze the brush of water, and let it soak up the bloom water. I find l8ad time 30 seconds is ideal, then face lather.
