Great product! I decided to bring my own rosin to pointe class, so I could always be sure I had some available. I bought an inexpensive plastic container with a lid (shoe box style) to store it in. You only need a small amount of rosin in the box. Myself and fellow dancers, all take turns using the rosin. I keep the plastic box full of rosin, in a plastic bag (grocery bag), when I'm not using it. This helps keep it separate from other items in my dance bag.
I was satisfied with this rosin, but it's huge! It's the size of my forearm! I have been having problems with falling on pointe lately, so I ordered this, used it in class, and immediately felt a difference. I liked that it was crushed, but I had a hard time not spilling it all over the place. I thought that there would be something to help you dispense it. Overall though, five stars.
