Change bridge orientation to 180°.

A ridiculously loud miniature whistle designed to grab attention despite its tiny size.

Unlike a standard whistle, this design features four separate sound chambers, each with a different length. The combination of four different frequencies creates an unusually loud and distinctive sound that is difficult to ignore.

Small enough for a keychain, it's perfect as a fun novelty item, everyday carry accessory, or emergency signaling whistle.
