Describing Objects. A phone box.

I have to describe a phone box. 

A phone box is a small structure, red in England, with a payphone, which it was built to use it on any daily situations. 
It is used for call and it has the same functions as a normal phone but you have to enter a currency if you want to call. 
It’s made of iron. It has a door so that people dont listen to what you say and windows to let others know if the phone box is in use. The phone box has a printed guide to local phone numbers. 

The red phone box designed by Sir Giles Gilbert Scott, is a familiar sight on the streets of the United Kingdom. Traditional British red telephone box is still visible in many places throughout the UK, and in British colonies present. The color red was chosen to make them easy to detect.
