Using this guitar strap is easy. Just adjust the length to your comfort, ranging from 86cm to 145cm, and attach it to your guitar. When using on stage, make sure it's securely fastened. For maintenance, keep it away from sharp objects to avoid scratches on the canvas and leather parts. Clean it gently with a soft, dry cloth. If it gets dirty, you can use a mild soap and water solution, but be sure to dry it thoroughly to prevent damage. Don't expose it to extreme heat or cold for long periods as this can affect the leather and canvas quality.
