Using this tool bag is a breeze. First, open the extra-wide mouth to easily place your tools inside. You can use the 22 internal pockets and holders to organize different tools separately. When carrying, you can use the padded handle or shoulder strap for maximum comfort, and the long handles let you carry it open. As for maintenance, keep it away from sharp objects to avoid tears. If it gets dirty, you can wipe it clean with a damp cloth. In case of water exposure, don't worry as the 100% waterproof base will protect your tools. Just let it dry naturally. Remember, it has a 1-year manufacturer warranty, so if you encounter any issues, contact the manufacturer.
