These Graypants Chrona Dish Pendant Lights are easy to use. Just hang them up in a dry location. You can choose to hang them alone for a simple look or cluster them together for a more dramatic effect. Over time, the brass part of the pendant may start to tarnish and look dull. Don't worry, you can use a regular polishing cloth to clean it up. If you want to keep it looking shiny for longer, you can seal it with wax. But remember, never use aggressive detergents on the brass as it can damage the finish. And if you're not satisfied with your purchase, you can return it within 30 days.
