Brushes are available in many different qualities. If your needs call for an economical set of paintbrushes, then Real Value brushes by Princeton Art & Brush Co is right for you! Available in both long-handled brushes for oil painting and short-handled brushes for acrylic, watercolour and tempera painting, these brushes come in sets.

These paintbrushes are a more affordable alternative to buying brushes individually and are often considered "student-grade". In real-world applications, this means that they commonly do not apply paint as perfectly as a better quality art brush and may lose a few hairs in your painting. That being said, they are perfect for situations when a more expensive brush is not called for.

Varying from the pack to pack, the bristles are made from: 

• 6614S2  - 4 PCS/SET
• Brown Nylon
• For acrylic and watercolor painting
