Check if sanitary napkins contain fluorescent agents

How to use a highlighter to detect sanitary napkins:

In the dark, lay the sanitary napkin flat and use a purple light to illuminate it from top to bottom. The distance between the purple light and the sanitary napkin is about 1 centimeter (similar to the usual operation method of lighting RMB). If it appears fluorescent green (like a fluorescent rod, bright green), it contains fluorescent agent.

Some sanitary napkins use concave-convex punching fabric on the first layer, which can be torn open for observation, resulting in more intuitive detection results.
