Using these bird cage products is a breeze. If you're using them as gift card holders, just slide the card into the cage. For hanging lanterns, hang them up by the ring and place a small light inside. As candelabras, put a small candle in the cage. If you want to use them for small birds, make sure the cage is clean and safe for the bird. When it comes to maintenance, keep them away from moisture to prevent rust. You can wipe them with a dry cloth regularly to keep the gold shine. Also, be careful when handling them as the iron edges might be sharp. Enjoy using these beautiful and versatile bird cages in your home or garden!
