This wholesale two-piece set includes dual-chamber survival whistles in champagne gold and silver frosted aluminum finish, each matched with metal connecting chain and polished split key ring for easy hanging on keys, backpacks, life jackets and emergency kits, suitable for bulk factory supply orders.

Crafted from lightweight aviation aluminum alloy with independent double air tube design, the whistle generates loud dual-frequency penetrating sound with long-distance propagation capability. Its distinct high-volume tone can cut through wind, fog and dense vegetation, ideal for camping, hiking, boating, pet training and emergency SOS rescue signaling.

Frosted anodized metal shell boasts premium rust-proof, scratch-resistant and fade-resistant properties, delivering steady stable sound output under rainy, damp, waterside and harsh wild environments without oxidation or discoloration. Slim streamlined ultra-light body adds almost no extra burden for long outdoor trips and daily carry.

All blowing contact edges are finely polished into smooth rounded curves to prevent lip chafing during prolonged continuous blowing. Seamless one-piece integrated construction contains no loose fragile internal components that jam or fall off, easy to clean of outdoor dust and water stains.

Cost-effective bulk wholesale outdoor EDC safety gear, widely applicable for outdoor retailers, camping stores, pet supply shops, first-aid kit manufacturers and household emergency reserve supplies.
