First thoughts were Windsor & Newton (enough said). Possibly the best model brushes in the world? The points on these are fantastic so you can use a brush several sizes larger than you expect for a given level of detail. Feel good in the hands.
They are an excellent choice of brushes but price wise they are steep. Though it’s always good to have the right tools for the job! Worth the investment.
Overall Great brushes, they are very thin. Great for miniatures.
