SILVER STAINLESS STEEL WHISTLE WITH KEYCHAIN

– With the two-sound-chamber design of the emergency whistle, it is easier to blow and then produces a loud sound up to 120db, enough to call for help.
– No built-in pea means no moving parts, nothing to obstruct sound, and nothing to jam, break, or freeze, offering excellent airflow in any conditions.
– Made of food-grade 304 stainless steel.
– Compared with plastic whistles, it is more durable. No matter how you use it, it always looks like a new one.
– Product Dimensions: 9.30 x 1.35 x 0.84 cm; 0.05 kg
