Wick cutting scissors
If you often light candles, you should definitely get a wick cutter.
You have probably already experienced that during the burning of the wick, small or large charred spheres are sometimes formed. In this case, the flame of the candle flickers back and forth, burning with a great flame, because the little sphere itself is already burning!
This is not very lucky, because this quasi-"garbage" will fall and damage the body of the candle and the melted candle wax will flow down the side - in fact, onto something flammable, e.g. if it falls on a tablecloth, it can even cause a fire!
These scissors cut very well, and are designed for this purpose: with its small, curved part, it catches the cut piece of coal and you can easily take it to the trash can*.
(*rinse it with a little water first to make sure the little embers fall asleep!)
The flame of your candle will also thank you right away, it will start burning normally again, returning to the original burning time :)
