Preparing to light your oil menorah is as easy as a "snap." Ner Light is pre-filled with olive oil in multicolors. Simply snap off the top of the vial (already pre-scored for a quick snap) with the snapper tool included in the pack. The wicks are guaranteed to burn for at least 3 hours. Each night another family member can choose the color combination. The best part, you don't need to worry about the flames burning out as the wicks are held in place by the glass vial. Each triangle box contains 44 vials for the entire holiday.
