Setup: The Valentino Fold Over Divina Bag requires no assembly. Simply unpackage it and it's ready for use. Before first use, gently open and close the button fastening a few times to familiarize yourself with its mechanism. Compatibility: This bag is designed to carry small personal essentials. - Smartphones: Most standard smartphones will fit, but larger "Plus" or "Max" models might be a tight squeeze or require careful positioning. - Wallets: Slim cardholders or small compact wallets are ideal. Bulkier wallets may reduce the space for other items. - Keys: A standard set of keys can be easily accommodated, perhaps within the internal pocket. Care: To maintain the pristine condition of your Valentino Fold Over Divina Bag: 1. Cleaning: For general cleaning, wipe the exterior with a soft, dry, lint-free cloth. For minor marks, dampen the cloth slightly with water. Avoid harsh chemicals or abrasive cleaners, especially on the metallic parts. 2. Storage: When not in use, store the bag in a dust bag (if provided) or a soft cloth pouch in a cool, dry place away from direct sunlight. This helps protect the material and metallic elements from fading or tarnishing. 3. Preventing Scratches: Be mindful of rough surfaces that could scratch the metallic logo or the bag's finish. Avoid overfilling the bag, as this can strain the material and fastening. 4. Chain Strap Care: Periodically check the chain strap for any twists or knots. Gently untangle them to prevent damage.
