Goal post and flag assembly can be painted as required of particular country or else same white goal post can be used with multiple flags interchangeably. For now I have included flags for Brazil, Switzerland, Argentina, Mexico, Netherlands and Spain. Going ahead I will be adding more flags. Meanwhile please vote for your choice of flag if you want me to include that at priority. I have also customized finger boots with alphabets A-Z.
