Candles with built-in matches (not "fuel-efficient lamps")

This is an interesting design. Lighting a candle is a good idea when you have a power outage or want to increase the atmosphere for some reason, and you are often looking for matches or a lighter. With a candle like this, you don't have to worry about it. This candle has a box of matches set at the bottom, which is a really handy thing to light your candle. Isn't that very human?

However, one thing is that this candle, although it can be used for a full 40 hours, but the price is not high, asking $18.00, is not a "fuel-saving lamp" ah.
