Because households of the day were lit by oil lamps and candles, Victorian candles often made from tallow or whale blubber had wicks that didn't burn away, so the cotton wicks needed to be frequently trimmed in order to keep the flame a reasonable size.
 
This is a beautiful silver plated candle snuff/ wick trimmer with original tray.
 
The condition is good.
 
Dimensions of snuffers: 18cm long
