Spello-tape is an adhesive tape that was used in the Wizarding world to fix objects that either could not be fixed by a spell, or when magic was not deemed appropriate to the situation. In 1992, Ron Weasley used Spello-tape to fix his broken wand, and Ginny Weasley used Spello-tape in 1994 to fix one of her textbooks. In addition, Harry found some Spello-tape in Dolores Umbridge's office.
Behind the scenes
Sellotape is a British brandnamed cellophane adhesive tape. It is similar to Scotch tape in the U.S. This is an example of the numerous puns used in the books.
