This set includes two functional spy tools: the Spy Labs Secret Voice Recorder and the Spy Labs Voice Changer. The wrist-worn recorder stores audio securely, requiring two included keycards for playback to prevent unauthorized access. The voice changer modifies 12-second recordings with adjustable pitch and speed settings for voice disguise. Designed for ages 8+, these tools encourage role-playing as detectives while introducing basic surveillance concepts. The Spy Labs product line offers additional gear for forensic and tracking activities, supporting extended investigative play scenarios. Both devices operate with simple controls for easy use.
