Arbovellum

Arbovellum was a type of stationery paper used on the Mid Rim planet Naboo. In 32 BBY, the girl Tsabin received three acceptance letters written on arbovellum after leaving the Theed Conservatory music school, inviting her to sit on the back row of an orchestra. However, she felt that the letters were pretentiously written and threw them away, choosing instead to become a handmaiden of Queen Padmé Amidala of Naboo.
