2 Pack Tactical Double-Tube Stainless Steel High Decibel Survival Whistle Keychains, Black & Silver
Directly supplied from Yiwu factory, this set includes two heavy-duty rescue whistles in matte black and matte silver stainless steel finishes, each fitted with matching metal chain and split key ring for keys, backpacks, camping gear and emergency kits.
Constructed from thick solid stainless steel, dual independent air chambers generate ultra-loud high-decibel dual-frequency sound with powerful long-distance penetration. The clear distinct tone cuts through wind, forest noise, fog and rubble, ideal for camping, hiking, mountaineering, travel and disaster SOS rescue signals.
Angular hollow tactical shell fixed with star locking screws enhances structural strength and impact resistance. Matte anti-corrosion surface resists rust, scratches and fading, maintaining stable sound performance in damp, rainy, muddy wild environments without oxidation.
All blowing ports are precision polished with smooth rounded edges to prevent lip chafing during long continuous blowing. Screw-assembled structure avoids loose internal parts jamming or falling off, with long service life for frequent outdoor standby use.
Cost-effective bulk wholesale EDC lifesaving tool from Yiwu factory, perfect for outdoor retailers, campers, hikers and household emergency preparation storage.
