This rosin reminds me of the rosin that I used when I first started playing (many years ago). It still adds a nice bite to the bow, which is great for up-tempo lively playing. It's also very easy and clean to use as the rosin block has a thin cork covering on the bottom and two long sides, which totally avoids getting sticky fingers. Only the red case has changed - when I was a kid it was cardboard, and now it's plastic - it would be nice if they went back to cardboard.
