Here’s an example of an accident waiting to happen:
When the candles burn down just a little farther, those METAL HOLDERS are going to get so HOT that they will cause BURNS on the bound dude’s skin.
If you are going to do something like this, use candles without those metal holders, and also cut the metal wick holder out of the bottom of the candle so THAT does not heat up and cause a nasty burn.
Also avoid expensive beeswax candles, which burn at a much higher temperature. And try not to burn the house down while you are at it.
Now you know (in case you didn’t already).
