Using your Ferm Living Kurbis Asymmetric Washi Paper Lampshade is easy. First, you'll need to get an E27 LED light bulb since it's not included with the lampshade. Once you have the bulb, install it into the lampshade. When placing the lampshade, pick a spot in your room where you want to add a warm and charming atmosphere. Remember, this lampshade has a unique asymmetric design, so you can position it in different ways to create different looks. As for maintenance, it's simple. Just wipe it with a dry cloth regularly to keep it clean. And in case you're not satisfied with your purchase, don't worry. It's covered by a 30 - day return policy.
