Using this Klein tool bag is a breeze. Just unzip the heavy - duty nylon zipper and start placing your tools inside. It's great for keeping different types of tools organized. When you're done, zip it up and you're ready to go. As for maintenance, you can simply wipe it clean with a damp cloth if it gets dirty. Avoid exposing it to sharp objects that could tear the Cordura® fabric. Also, don't overstuff it as it might damage the zipper or the padding. Keep it in a dry place to prevent any mold or mildew from forming.
