SonicSpinner：Titanium Emergency Whistle with Fidget Slider

SonicSpinner is a sleek titanium whistle with a fidget spinner design, combining high hardness, lightness, and corrosion resistance with a compact, fashionable look. It’s loud enough (120dB) to be heard over a mile away, making it perfect for survival, camping, hiking, or emergency signaling. Dual-purpose as a necklace or keychain, it’s also a great stress-reliever for adults during daily life.
