These are creative bulb - shaped string lights. Each clear bulb is like a tiny transparent world, with simulated snow, pine needles, and red berries inside, creating a strong Christmas atmosphere. The bulbs are connected by thin wires, and there is a small battery box (presumably for power supply). When lit, the warm light shines through the bulbs, adding a cozy and festive touch to the decoration. They are perfect for Christmas tree adornment, home party decor, or creating a charming holiday ambiance in any space.
