Cecilia Violin Signature Formula

I loved this rosin for about 5 minutes but unfortunately I am extremely allergic to it. I am allergic to most rosins but not usually this badly. However for the 5 minutes I used it I absolutely loved it. It grips perfectly and really mellowed the sound of my fiddle. I gave it to a friend who also thinks it is fantastic and uses it all the time. Very sad I could not use it myself.
