12 inch jumbo glow sticks provide bright illumination and are designed for extended visibility. Under optimal conditions, the glow effect can last up to 10–12 hours. These glow sticks are waterproof, non-toxic, and do not generate heat. They require no batteries or external power source, making them ideal for outdoor activities such as camping, festivals, parties, concerts, and emergency lighting situations. Each glow stick is safely packaged in a durable cardboard tube that protects against light and heat exposure, helping to prevent premature activation and ensuring product quality. The chemiluminescent technology produces a safe, cold light suitable for use in various environments, including underwater applications. The glow sticks measure approximately 15 x 300mm and are made from PE material. They emit a vibrant green glow and are intended for single use. Package includes 10 glow sticks. No other items are included. Note: The liquid inside the glow stick is not edible and may cause staining if leaked. In case of leakage, clean affected surfaces promptly. If contact with skin or eyes occurs, rinse thoroughly with water. Seek medical attention if irritation persists. Due to lighting effects and display variations, the actual color may differ slightly from the image. Size variations of ±1–3 cm may occur due to manual measurement.
