These floating candles will bring the magic to your Harry Potter themed event or room Ddecor! 3 Sets of 12 (total 36 candles + 3 remotes) We used them for an epic Hogwarts party. Candles have tiny holes in tips which we threaded fishing line through to hang the lights from the ceiling. Each LED candles requires AA Batteries. 6.7 inch tall and 1 inch in diameter. Purchased new on Amazon these are $25-35 per set and don't have the threaded holes drilled for straight hanging. Candles can also be used for general decor or religious vigils. Will be mailed same day as purchase.
