> Later, the surfaces of those bullae were impressed with the tokens to be sealed inside so that a bulla’s contents could be divined without having to break it open. Once it became apparent that the signs on the outside were as useful as the tokens on the inside, the tokens themselves became surplus to requirements
My understanding is they continued to use bulla. They would create a clay version of a contract and then seal it inside of a clay "envelope". Then the contract would be replicated on the outside of the envelope. People could read the outside of the envelope to see what the contract stipulated, but if there was ever a disagreement (charges of the outside having been altered) then the envelope could be broken open to check the version inside to see if it matched the version on the outside.
