Bumbu originally making Bible Paper, 1700's. Shifted to making cigarette paper. This item measures 2" square and held the Bambu papers. Made from a specific type of the African Acacia tree, the sealer tip is a completely chemical free substance, no additives of any kind. Passing the highest known food standards the gum has neither taste not calories. This allows the paper to experience and enjoy their tobacco in it's most natural state. This metal container is marked Bambu Made in Spain on the back and Bambu Alcoy on the front. Quite interesting piece of history.
