Many cruises offer "glow parties" where cruisers dance the night away with colorful lights and music. Whether for Carnival's 80s Rock-N-Glow Party, NCL's H2Glow, or your own themed event, these LED finger lights are easily secured to your finger tips with colored bands and glow for hours. Each pack contains four lights (1 each white, red, blue, green) with batteries installed and ready to go.
