Using your personalized acrylic car ornament is easy. First, remove the protective film from the ornament. You can then hang it in your car using the stainless - steel ball chain. It will add a lovely personal touch to your driving experience. If you want, you can also use it as a key hanger. Just attach your keys to the chain. When using it to decorate a briefcase or handbag, simply clip the chain to the handle. As for maintenance, keep it away from sharp objects to avoid scratches. You can clean it with a soft, dry cloth. If it gets dirty, use a mild soap and water solution, then dry it thoroughly. This will help keep your ornament looking great for a long time.
