These "undressed" tealights are designed for tealight holders and candle plates. They have no aluminum or tin holder and will burn clean and pure without any oxides emitting from their burning.
Please note: These should NOT be burned without a tealight holder or a plate of some kind as they may "run" at the end of the burning cycle. Melted wax is messy and does present a hazard as it is flammable.
