Notes
Named for its resemblance to the dry outer layer of an onion, onionskin is commonly used to create carbon copies of typewritten text, with additional uses in art and film animation. It is made from cotton fibers and/or bleached wood pulp. Despite its durability relative to its weight, it frequently requires special handling.
