Try one for yourself.)FAQ:To address what's mentioned in the feedback: don't worry, this item is  using REAL high quality wolf hair.  However, it's not pure (100%) wolf hair. Usually when not defined, the wolf hair is at least 80% or even more (depending on the brushes). This is common for any wolf hair brushes. Wolf hair is very expensive and short. For  a 4.4cm long brush,  PURE wolf hair would cost way much more than this brush. Also, additional hair is sometimes added  so the brush has a better structure.
