Description
This novel emergency whistle is integrated with a clip. It easily clips on & off your keychain, without fiddling with the key ring or a separate clip.
There is a small (0.2 mm) gap in between the two sides that allow the clip whistle to slightly open for the clip action; the small gap doesn't affect the whistle sound or loudness.
