- Small but practical: Adds a simple safety and communication tool without bulky gear.
- Lightweight carry: Barely adds weight to everyday keys or outdoor kits.
- Multi-use utility: Useful for coaches, hikers, dog walkers, commuters, and event staff.
How to use
- Attach it to a split ring, lanyard, cord, or bag clip.
- Keep the opening clear from lint, dirt, or debris.
- Blow firmly through the mouthpiece when signaling.
