Romans used to write notes with a pointed bronze "stylus" scratching them in wax.
They had tablets from hollowed out wood and hardened beeswax inside.
These tablets come in pairs and can be folded down like a diptychon.
To write another message, notes were erased with the flat end of the tool the Romans carried with them.
Size of each tablet is 20 cms x 12 cms (8" x 5")
Weight of the pair : 400 g / .9 lbs.
