Using this case is easy. First, open the high - quality YKK zippers and gently place your Bb clarinet in the plush - lined, contour - molded nest. Make sure it fits snugly. Then, close the zippers. You can carry the case by the reinforced handle or use the comfortable shoulder strap for long - distance travel. Store any small items like reeds or cleaning tools in the exterior pocket. When it comes to maintenance, keep the case dry. If it gets dirty, use a soft, damp cloth to wipe it clean. Avoid using harsh chemicals as they may damage the EPS polyfoam or the case's finish. And always be careful when opening and closing the zippers to prevent them from getting stuck.
