Using this guitar strap is easy. First, adjust the length according to your preference and the instrument you're using. You can do this by simply pulling on the strap to make it longer or shorter. When attaching the strap to your guitar, make sure the nylon end tabs are securely fastened to the guitar's strap buttons. As for maintenance, you can wipe the strap with a damp cloth occasionally to keep it clean. Avoid using harsh chemicals as they might damage the polypropylene webbing or the nylon tabs. Also, when not in use, store the strap in a cool and dry place. This will help maintain its quality and ensure it lasts for a long time.
