As protests continue in Tahrir, vendors of everything from gasmasks, tea, batatas and little flags flock to the square to supply the protesters with any sustenance they may need.
Some vendors sell pins and buttons that proudly proclaim the intentions of the protesters, and their messages change from day to day and cause to cause, always in sync with the issue of the day.
These are the pins from 25 November.
