Using this Gator hardshell case for your 3/4 violin is easy. Just open the case, gently place your violin inside, and close it up. Make sure the violin fits snugly to avoid any movement during transport. When carrying the case, hold it by the handle or use the shoulder strap if available. As for maintenance, keep the case clean by wiping it with a soft, dry cloth regularly. Avoid exposing the case to extreme temperatures or humidity as this can damage the ABS material. If there are any spills, clean them up right away. Don't over - stuff the case with extra items as it may put pressure on the violin and damage it. Also, check the latches and hinges periodically to ensure they are working properly and securely.
