Included are 2 white whistles! You can rattle can prime and paint in any color desired! If you absolutly have to have custom colored 3d filament I can get it but each color will run approximatly $25 a whistle. I would recommend spraying in whatever color is desired! 
 
Ahoy mateys! The Cap'n Crunch Bo'sun whistle, originally a prize toy in boxes of cereal, became the stuff of legend as a tool for phone freaks (phreakers) delving the depths of telecom networks in the 1960s. Because it emitted a tone of 2600Hz, the same tone used by AT&T's system to signal a line to open and prepare for connection, it could be used to manipulate the system and make free calls. The 2600Hz signaling protocol is no longer in place, but phreakers' use of the whistle remains a touchstone of ingenuity in the history of hacking. Re-live the excitement with this 3D printed replica!

The fabled phreaker John Draper, who popularized use of the Cap'n Crunch whistle for network exploration, shows how he used to open a phone line and dial a number in this video: https://vimeo.com/112783389
