These are decorative string lights with bulb - shaped ornaments. Each bulb has a pink, glitter - filled glass (or similar translucent material) exterior and a metallic - look base. The bulbs are connected by thin wires, and they emit a warm, glowing light from the base area. They can be powered by batteries (as suggested by the visible battery pack), making them suitable for adding a romantic, festive ambiance to various settings like parties, home decor, weddings, or holiday decorations.
