"Robusto" from Italian means "strong" - and this is what the bristles of the 1176 series brushes are like. The "Hobby Robusto" series is distinguished by very strong black synthetic bristles and red lacquered handles.
Robusto bristles are resistant to long-term use, ensure comfortable paint application and are easy to clean. Robusto brushes keep their shape very well. They are also recommended for heavier, rough surfaces such as wood, cardboard, ceramics etc. Robusto can be stored in water for a long time without compromising the quality or shape of the bristles.
