Pirastro Tonica Violin/Viola Rosin
Pirastro Tonica rosin is a metallic orange, medium-hard rosin. It was developed to be used with Pirastro Tonica Violin strings but can be used successfully with any make of strings.
Each cake of rosin is glued onto a soft cloth which then is attached to a hard plastic grip. This prevents the fingers of the musician getting covered in rosin dust and also makes it easier to apply the rosin evenly.
