   All I can tell you is the material is black, it's not metallic, it's not   
   natural hair, it's very stiff, and not only does it not shed any particles   
   whatsoever, it doesn't wear out.  A bit.  At all.  It also doesn't react to   
   IPA, acetone, or toluene. I've    
   seen those fiberglass pens that come with 10 refills.  The Chemtronic brush   
   bristles are only a few mm long but they don't wear down.    
      
   Chemtronics answered  my email and said they don't sell the brushes separately   
   as I suspected.  I have been unable to find them by searching images or found   
   any other product that uses them.   
      
   For now I've cut some acid brushes down to about 5 mm to duplicate the   
   stiffness (more or less).  I guess I'll have to buy some cans of Fluxoff to   
   get a couple more.  I think I'll drill them and attach a long lanyard to them   
   so I'm less likely to    
   misplace them in the future.
