New!! Glow-in-the-dark safety whistle for elementary school students

This is a crime prevention whistle shaped like a squid with a glow-in-the-dark function.

Features: Not only can it be used as a whistle to make sound, but it also uses glow-in-the-dark material, so it shines in the dark, increasing visibility at night.
Uses: It is used as a crime prevention item to attach to children's backpacks and bags, or as an emergency disaster preparedness item during disasters.
