This set is a set of two 4” burnt ivory colored, wax-coated taper candles. Each one has a flame-shaped tip and built-in timer that stays on for 6 hours and then off for 18 hours. They twist at the bottom to turn on/off and to insert batteries. They are for indoor use and require 1 AA battery (not included) to operate. Each taper candle measures 4" high.
