+since ``bytes1[]`` adds 31 padding bytes between the elements. As a general rule,
 use ``bytes`` for arbitrary-length raw byte data and ``string`` for arbitrary-length
 string (UTF-8) data. If you can limit the length to a certain number of bytes,
 always use one of the value types ``bytes1`` to ``bytes32`` because they are much cheaper.
