Natural hair pointed brush for thin line decorations. NABA brushes are made of Kolinksy hair of highest quality. (Kolinsky is a rare species of weasel in Siberia. Collecting the hair of animal is very difficult, so these brushes are much more expensive than synthetic brushes.) The advantage of natural hair is that it is very good absorbent and resistant against chemicals. Our brushes are individually designed, with a logo, and with a durable metal handle and cup.
