This is a superb cello rosin and easy to use as well. I find it particularly valuable as the rosin is set in a wooden channel that makes movement along the bow so much better directed. You simply cannot go wrong with this superior product. A++++
I purchased this cello rosin to try on my violin strings to see if I could get a warmer tone and I am very happy with the results. It lasts about a week and has improved my sound a lot. I will keep using this product.
