These automatic candle extinguishers are a neat idea that allow you to automatically extinguish a candle after a predetermined time interval.
Simply slip the Swedish candle extinguisher onto a candle, and the spring-loaded cap will automatically be held in the open position. However, as the candle burns down, there will come a point where the spring-loaded cap will no longer be held open, and the spring will cause it to close, over the flame, and put the candle out.
You could use this product to extinguish the candle after a set period, you could use these as a safety feature if the candles were placed in a wreath or decoration, and you didn't want the candle to burn down so far that there was a danger of setting the decoration on fire.
PROTECTION DESIGN: The lid of the Swedish candle extinguisher is raised towards the top to ensure that the wick is not damaged when it is closed and to prevent the candle from spilling around.
ADJUSTABLE SIZE: Candle extinguisher fixed circle can be manually adjusted for size, suitable for use in the diameter of 2-2.2cm / 0.78-0.86inch candle. SPECIAL GIFT: For lovers of quirky gadgets, the automatic Swedish candle extinguisher would make a great gift.
