Glenn Dicterow and his letter about CECILIA Signature Formula

Signature Formula

“Strong but not too grainy.”

“It creates a full and rich sound. It also lasts longer so I don't have to rosin my bow as often. I have tried at least 30 different brands of rosins over the years, but CECILIA Signature is my favorite. Bravo!”

“CECILIA rosin has a unique quality that enables me to expand the ranges of tone and bow articulation. Its consistency in various performance environments makes it second to none.”
