The Walkie Talkies by Spy X is a Walkie Talkie Set designed for children to engage in role-playing as they use the gadget to play spy with friends. The package includes a pair of Walkie Talkies. You will need 6AAA batteries to power the devices. Batteries are not included in the package. It has an antennae range of approximately 20m to 30m. Each Walkie Talkie has a Push to Talk button, a call button, a long-range antenna and a belt with a clip to easily attach the device to your clothes while you are on the move. To use the Walkie Talkie, switch on both the devices. Then one user pushes the button and talks and releases the button to hear. The distance between the two devices should not be more than the acceptable range, or else the devices will not work. If the voices start to fade away, then you can extend the antennae to increase the clarity of the voice. You can use the call button to get the attention of your friend holding the second Walkie Talkie. The design and size of the Walkie Talkies are perfect for children to comfortably hold it in their hands while they are on the move as secret agents. The package measures approximately 23cm high and 18cm wide. The item is recommended for children over 6 years old.
