Using this Fender Mustang Micro carrying case is a breeze. First, open the zippered case. Put your Mustang Micro in place and secure it with the interior elastic band. Then, place the charging cable next to it and use the same elastic band to keep it steady. Put your wired earbuds in the interior mesh pocket and use the elastic band there to keep them from falling out. When you're going out, you can either put the case in your gig bag or backpack, or use the carabiner clip to attach it directly to your gig bag. As for maintenance, keep it in a dry place. If it gets dirty, you can use a soft, damp cloth to gently wipe the exterior. Avoid using harsh chemicals as they may damage the 3mm EVA foam shell.
