Flex-tape served as a repair substance for starships. Back in 382 BBY, the human prospector named Dass Leffbruk had the impression that his father's starship, known as the Silverstreak, was only being kept intact by flex-tape and wishful thinking.
The reference to flex-tape appeared within Quest for Planet X. This junior novel was authored by Tessa Gratton and released in 2023, forming a segment of the Star Wars: The High Republic multimedia initiative's Phase II. In our own reality, Flex Tape is a product offered by the adhesive manufacturer Flex Seal's.
