No idea!

But I have the Semogue 1305- perfect for soaps and the

Semogue 2000 - excellent for creams and very good for soaps.

They are the only boars I have tried. And I don't intend to look for more.

I have three expensive badgers which are a delight to use. But boar brushes are much better value for just getting a job done.

And no sign of hair loss after 3 months. (Brushes, not me!)
