Slim candles (6)
I believe the answer is:
tapers
'slim candles' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tapers that I've seen before include "Narrows towards the end, like a candle" , "Prates about candle lighters" , "Makes or becomes gradually narrower" , "Diminishes gradually" , "Long thin candles" .)
