Cecilia (formerly known as Andrea) Cello rosin produces several varieties and this special cake is formulated to provide the best of both worlds. This unique combination creates the optimum balance for sound and bow control. The Sanctus formula is hydrogenated to have excellent oxidation resistance, to ensure consistent quality performance experience throughout its usage.
The outer ring formula provides a smooth bowing experience and a focused sound on the strings. The center formula kicks in when the musician pushes the bow to pull more power and gutsiness.
