I bought a pair of Melbourne jogging pants. The seller said that these are reflective pants. It can emit fluorescence after being illuminated by a lamp at night. . . But I bought it, but it didn't shine.
This is normal. It's called fluorescent pants, yes, but it's not fluorescent. This kind of cloth is the kind of traffic police uniform. Even in a dark place, as long as there is a little light, it looks dazzling and obvious. If you are in a completely dark place, it will definitely have no effect. What is needed is light, landlord, you misunderstood. .
I bought one too. At first, like the landlord, I went to the store and asked, and the result was really like this. .
