1. Usage Method: Fluorescent sticks are composed of two parts: a plastic tube containing different liquids and a glass tube. When using, gently bend the fluorescent stick, break the glass tube in the plastic tube, and shake gently to allow the two liquids in the glass tube and the plastic tube to fully mix, achieving a better light emission effect.
2. Luminescence Time: The luminescence time of the glow stick is 4 hours to 12 hours. The length of the luminescence time is inversely proportional to the ambient temperature, and inversely proportional to the initial brightness.

Based on these characteristics of the glow sticks, by placing the already lit glow sticks in a low-temperature environment (such as a refrigerator or freezer), we can inhibit the chemical reaction between the two liquids in the glow sticks, and they can be reused after removal.
3. Safety: Professional institutions have tested: The chemical substances used in the fluorescent sticks are non-toxic, harmless, and non-radioactive before and after the reaction, and are not flammable or explosive items.
4. Transportation and Storage: During the transportation and storage process, fluorescent sticks should be avoided from high-temperature exposure and gravity impact or falling. This is to prevent affecting the fluorescent stick's light-emitting time and brightness, and to avoid breaking the glass tube inside the fluorescent stick, which could cause the fluorescent stick to light up prematurely, leading to the ineffectiveness of the fluorescent stick.

 5. Product color: Currently, we can offer colors such as bright red, yellow, green, blue, orange, and pink. These are the most common colors, and you can choose any one of them when purchasing.

6. Product Usage: Lighting and decoration at concerts, dance halls, birthdays, gatherings, weddings, banquets, evening parties, festivals, celebrations, outings, and field camping. Due to the fact that the glow sticks are chemical luminescence, they do not require high temperatures or radiation, and do not need to rely on power or other energy sources, they are particularly suitable for: diving, rescue operations, exploration, field activities, high altitudes, and hazardous work environments. Glow sticks are widely used in bars, concerts, and various large-scale celebrations, bringing more excitement to people's lives. Abroad, glow sticks are widely used in various festivals, such as Halloween, Carnival, and Christmas. In domestic national legal public holidays, especially National Day.

Caution: The liquid in the glow stick is not edible and has a certain adhesive property. If it leaks, it can easily contaminate furniture, floors, clothing, skin, etc. If any of the above occurs, it must be cleaned in time; if the liquid from the glow stick enters the eyes, it must be washed with clean water immediately or seek medical attention.

 Therefore, it is strictly prohibited to pierce the plastic tube of the fluorescent stick with a knife or scissors; it is also prohibited to bend the fluorescent stick excessively, to prevent the liquid from leaking out of the fluorescent stick. It is forbidden to pierce the plastic tube of the fluorescent stick with a knife or sharp tool, and it is especially forbidden to follow the trend of the times, applying the liquid from the fluorescent stick to the body. Especially pay attention not to let children ingest it.
