NB! Brass is a natural material that changes based on its surroundings, and as a result, the surface of your brass product will become darker and less glossy over time. This is a natural process that allows each lamp to develop its own individual patina. If you want the surface to stay glossy and light, you can use a brass polisher. Note that you need to use a special polishing product made for brass or copper with as little abrasive as possible. Use a soft cloth to polish your product, and make sure to use the included gloves, so you don’t leave fingerprints.
