Using these artificial eggplant roses is a breeze. For wedding bouquets or centerpieces, simply arrange the roses and leaves as you like. Since the roses have a thin wire stem, you can bend them into different shapes or cut them to the desired length. When using them for DIY projects, such as scrapbooking or making souvenirs, the detachable rose heads give you more flexibility. As for the off - smell, don't worry. Just open the box and let the flowers air out for a while. To maintain these beautiful flowers, keep them away from direct sunlight to prevent color fading. Also, avoid getting them wet as it might damage the latex foam and silk materials. With proper care, these roses will stay looking great for a long time.
