Hidersine 3V Rosin Violin / Viola

Though not being fantastic, this rosin is miles from being unsatisfactory. It allows for a smooth grip and slide, and is easy to clean. The rosin clings on to the ribbon nicely, and isn't frustratingly sticky (though obviously still sticky).
A minor complaint would be that the tin it comes in is a bit difficult to open, but as I said, this is incredibly minor. It also took a bit of work to get through the shiny top layer at first, but this is too be expected from most rosins.
The price also makes it great value for money, so there is no reason for one playing for pleasure to purchase this bow.

If you want to skip the three above paragraphs, just read the title of the review: Good rosin :)
