I'm a first time cello player/rosin user, and picked this Pirastro after researching reviews and price comparisons. Appears to have been a good choice. It is conveniently small but large enough to seem it'll last forever. The rosin is surrounded by a high quality white cloth, attached via the bottom plastic base. I've kept the little box it comes in as a container, but if that wears away I'll need to find something else to keep it in. As for performance, after many (~50 up & downs) applications of the new rosin to my new bow, and a few strums to let the excess fly away, I am very satisfied with the grip and tone. I whole heartedly recommend this product; however, this is the only rosin I currently have experience with.
