Our 2.5" diameter candle covers are made with a heavy PVC core for strength. They are entirely hollow with an interior diameter of 2-1/16". Each one is hand made from genuine beeswax. This candle sleeve is designed for when you would like a more substantial look on your lighting. They are also used as a unique filler in table lamps and floor lamps. Please note that this candle is not designed for the bulb to be mounted on the interior. For interior mounted bulbs please see our Translucent Candles. We custom manufacture each one by hand to your specifications so please allow 10-14 business days for completion. If your height is not shown we can manufacture any custom height up to 10" tall.
