Apply Pirastro Goldflex rosin to your bow hair, and youll enjoy a lock-tight grip on your strings with zero scratchiness. This hard, gold-colored rosin is tailor-made for steel strings, although players with synthetic and gut strings will appreciate the reliability of this rosin in hot, tropical climates. We often recommend harder, dryer rosins like Pirastros Goldflex to concert hall-bound performers, given its ability to withstand all measures of temperature and humidity. Goldflex rosin comes in a chamois cloth attached to a hard plastic grip to safeguard against sticky fingers during application. If you need high-quality, general-use rosin, you cant go wrong with Pirastro Goldflex.
