Violin Cases
Once you have purchased an instrument, such as a violin, you will definitely need a case to store it. However, cases are not only for storing the instrument once you finish practicing; they are essential for transporting and protecting it from shocks, crushing, humidity, rain, etc.
If you have purchased a studio or beginner's violin, it will most likely come with a case, but if the case does not meet your expectations, it's time to get another one.
If, on the other hand, you have purchased a handcrafted violin, the choice of the case will most likely be up to you.
