How to use: Simply put on the necklace and choose either the black or steel side according to your outfit. You can wear it on its own for a simple look or layer it with other jewelry. Attention: Avoid wearing it while doing strenuous exercise or in water, as it may cause damage. Maintenance: Use a soft cloth to wipe the chain regularly to keep it shiny. If it gets dirty, you can use a mild jewelry cleaner, but make sure to rinse it thoroughly and dry it well.
