Using the Klein 5190 tool pouch is super easy. First, decide how you want to organize your tools. You can put pliers in one pocket, screwdrivers in another, and so on. Slip the slotted part of the pouch onto your belt, making sure it's secure. It fits belts up to 1 - 3/4 inches wide. When you're done using your tools, just put them back in their designated pockets. As for maintenance, keep it away from excessive moisture as it's made of leather. If it gets dirty, you can use a soft, dry cloth to wipe it down. And that's it! This durable pouch will serve you well for a long time.
