In addition to the two main properties of solidity and lightness, other ancillary features of the case should also be taken into consideration when purchasing. For example, whether the case is designed to hold the violin in suspension, whether there is a hygrometer, whether there is enough space or a small box for accessories (such as shoulder pads, rosin, strings, etc.), whether there is a protective or rainproof outer layer on the outside of the case, whether there is a pocket for the music, etc. Lastly, you should pay attention to the quality of workmanship of the case and its cover, such as whether the zipper is easy to pull and whether the handle is firm. The durability of these things is also crucial.
