Using your new rhinestone backpack is super easy. Just open the zipper and start putting your stuff inside. Whether it's books, a laptop, or daily essentials, it's roomy enough to hold them all. When it comes to cleaning, use a soft, damp cloth to gently wipe the surface. Avoid using harsh chemicals as they can damage the rhinestones and the material. Also, try not to overstuff the backpack to prevent it from losing its shape. And remember, due to the Proposition 65 warning, handle the backpack with care to minimize exposure to the mentioned chemicals.
