Caged Kingdom connects prisoners with society, encourages productivity during incarceration and aims to make life better for the incarcerated and their families. You, the viewer, can then select which prisoners you would like to correspond with, both men and women, after viewing personal (interests, goals, etc.) and public (crime, release date, etc.) information. Once you have selected a prison pen-pal to correspond with, you have the option of sending your first message free of charge. Contact with prison pen-pals is then maintained via postal mail or programs like CorrLinks and JPay.
