Using your Makita 21-inch contractor tool bag is a piece of cake. Simply unzip the high-quality zipper and place your tools inside. You can use the three exterior pockets to store small items like nails or screws. When carrying, you can either use the durable handles or throw the shoulder strap over your shoulder for a more comfortable grip. As for maintenance, keep it clean by wiping it down with a damp cloth after use. Avoid exposing it to sharp objects that could tear the industrial fabric. Also, don't overstuff the bag to prevent damage to the handles and zipper. With proper care, your tool bag will last you a long time.
