Roman Wax Tablets/Tabulae/Diptychs were used for all forms of writing where the text was to be of no great length. The tablets were made often of wood (though sometimes of ivory) and had a hollowed out section into which was poured molten wax, which could then when hardened, be written upon with a metal or bone stylus. The text could then be erased using the flat end of the stylus and then rewritten upon. About 8 by 7 inches when opened. 4 by 7 inches when closed. 4 1/4 inch metal stylus.
