These SUPER cute Scent Truffles are for use in an electric or T-light oil/wax burner. Each truffle can be melted several times before all the fragrance has been used. Our trials gave 24 hours plus of burning time using 6 x 4 hour T-light candles- & we still had a good ‘scent throw’ left. After all the fragrance has gone – simply discard the remaining wax – & reach for another truffle. Ta – Dah ! Almost good enough to eat – BUT PLEASE DON’T !
