Aeien silk refers to a type of silk that was utilized in the production of clothing. When Jaxxon T. Tumperakki paid a visit to Lando Calrissian hoping to persuade him to put money into Tumperakki's fledgling shipping business, he was wearing a cloak fashioned from the least expensive aeien silk available. Jailyn Cirri was sold a cloak constructed from the identical fabric by the fashion expert Neshee.
