Promethean Everlasting Matches

Everlasting matches were as their namesake suggests, everlasting matches. They are made of Umbeka wood, the heat from the flame made the wood grow as fast as the flame consumed it, so the match would never burn down. They were created by the Eternity Perpetual Company of the the planet Umbeka. (TN: The Cabinet of Light, TDA: The Resurrection Casket)

In his first incarnation the Doctor often carried a box of these matches. (TN: Time and Relative) Later in his eighth incarnation he often utilised them. (EDA: Kursaal, Seeing I)
