Description
Please also take a look at my new Sports Fan Whistle - a full-fledged referee whistle with national colors. | I have also developed real Ultrasonic dog whistles at 20,000 Hz and above, which you can find here. |
Description:
This tiny whistle (only 4.8mm thick!) is extremely loud for its size and pretty sturdy. And it fits easily on any keychain.
I uploaded profiles for dual color and for single color prints.
WARNING:
This is an emergency whistle and not a toy! It's extremely loud which can harm the ears, so please protect your ears and don't use it near other people or animals!
