Dagger Brush - Princeton Neptune
Synthetic
 
Princeton has done it again.  Almost 2 years ago, Princeton gave artists a synthetic version of sable that was almost the equal of fine Kolinsky and is still the standard for performance for its rivals.   When they set out to create a synthetic version of squirrel they developed a brush that may actually out perform the natural version. 
 
Neptune is their thirstiest brush ever delivering oceans of color to the sheet.   Experts in natural hair have been incredulous that this is actually synthetic.
