Descrição

This ultra loud safety whistle is compact, reliable, and reaches up to 122.8 dB in real-world testing — making it an essential tool for outdoor survival, emergency signaling, or personal safety.
It produces a sharp, piercing tone that cuts through noisy environments, ensuring you’ll be heard when it matters most.

Designed for support-free printing, it prints cleanly and quickly with most FDM 3D printers. The keyring hole allows easy attachment to bags, belts, or lanyards.

Perfect for hikers, runners, campers, and urban commuters who value safety and simplicity.
