This is a handmade product made by simmering natural rosin for a long time, with no additives. It's made by pouring rosin onto baked goods. The performance is not sticky, but has a smooth feel, while still providing excellent grip on the strings. Because it's handmade, there may be some slight imperfections, but this does not affect the performance at all. It prevents the sound from distorting. Please give it a try. We have received very positive feedback from those who have purchased it. Cellists have also given it high praise, with comments such as "The strings grip like they're sticking, and the sound has gained transparency and amplified overtones." Thank you for looking.
