Riker’s Island green cup — part of a basic personal kit an inmate receives upon entering Riker’s Island prison. This cup has a multipurpose function allowing an inmate to shave, brush his teeth, drink water, or make a hot beverage to drink — using prison ingenuity — while in his cell. Often when prisoners “graduate” — leave prison — they bring their green cup with them both as a memento and a reminder. You don’t ever want to be put into a position where you have to use a Riker’s Island green up; or, to actually learn and experience how useful and versatile it is in the life of a prisoner.
