Sellotape was a commercial brand of adhesive tape. Harry Potter's spectacles were often held together with large amounts of Sellotape due to the number of times that Dudley Dursley had punched him on the nose.
Behind the scenes
- The Scholastic versions of Harry Potter and the Sorcerer's Stone instead use the term Scotch tape.
- A riff on the name was used for the Spello-tape used by wizards.
