Violin Cases
Once you've acquired an instrument, such as a violin, you'll certainly need a case to store it. However, cases are not just for storing the instrument once you've finished practicing; they are crucial for transporting and protecting it from impacts, crushing, humidity, rain, etc.
If you've purchased a studio or beginner's violin, it will likely come with a case, but if the case doesn't meet your expectations, it's time to get a new one.
If, on the other hand, you've purchased a handcrafted violin, the choice of the case will likely be up to you.
