Mini LED ball lights for balloons, table settings, gift and jewelry fillers, and Christmas, wedding, or birthday decor. This listing is the White; 10PCS variant, so you receive 10 lights. Each globe is a transparent plastic shell with built-in electronic components and measures about 1.7 cm (0.67 in) in diameter, small enough to drop inside a balloon or a clear ornament. Lighting mode: constant light (single color) or flashing (color). Power: 2 built-in AG3 button batteries per light; the batteries are non-replaceable, so each light works until its cells run down. Package weight: 210 g. Package dimensions: 200 x 200 x 50 mm (20 x 20 x 5 cm / 7.87 x 7.87 x 1.97 in). Care: keep the lights dry and do not immerse them in water; wipe the shell with a soft dry cloth. Store at room temperature away from direct heat. Contains small parts, so keep away from young children and pets.
