I still don't believe it. Mexican candles? This is a technology from ancient times; why would a candle made in Mexico in 2024 be any different from an American or Chinese or wherever candle?
Mexican candles probably aren't any different except they were involved in two fires the previous commenter was familiar with. Some cultures/religions use candles as part of their holiday observances.
Mexican kids knock over the religious candles all the time. One tragic event happened when a friend's house was engulfed in flames after a candle was knocked into the curtains and she suffocated protecting her children from the smoke, I think one child had really bad breathing problems too.
