The ACRA sports whistle has a durable metal body and a round resonance chamber with a ball. The airflow causes the ball to vibrate and creates a distinctive oscillating signal that can be used, for example, to start, interrupt, or end exercises and sports activities.
The small format easily fits into a pocket or sports bag. The eyelet at the end of the whistle allows you to attach your own lanyard or strap; the lanyard is not included in the package.
The whistle is a personal hygiene item, so always clean the mouthpiece before sharing. Dry the surface after use and store the product in a dry place. The price is for 1 piece.
