Papyrus Reparo is the incantation of a charm that can be used to mend torn pieces of paper. It is a variant of the Mending Charm, Reparo.
This spell was used by Newton Scamander in 1927 to restore a torn postcard sent by Tina Goldstein to her sister Queenie Goldstein in New York. This restored postcard informed Newt Scamander that Tina was in Paris (CG).
Papyrus is the Latin word for "paper" or “papyrus”, a paper-like material made from the papyrus plant. Reparo is the Latin word for “repair".
