Virgin Expandable Polystyrene (EPS) Beads Virgin EPS beads are the classic beanbag beads that have been around since the 60s, when beanbags were first introduced. These brand-new beads (as opposed to the recycled variety) are small, round, white and very light. Stuff them in your beanbag, have a seat and it is 1970 all over again. You are so retro! NOTE: Our EPS is CFC-free and meets the new RoHS (Restriction of Hazardous Substances) requirements.
