I HAVE BEEN PLAYING VIOLIN SINCE I WAS A CHILD. I JUST RECENTLY PURCHASED A NEW ONE AND THE BOW HAS TO BE ROSINED QUITE A BIT BEFORE YOU CAN USE IT. THIS ROSIN IS A HIGHER QUALITY AND WENT ON EASILY AND DID NOT CHALK TOO MUCH. THIS IS A GREAT CHOICE AND I HIGHY RECOMMEND IT. WELL DONE TO THE SELLER!
