Scrivenshaft's Quill Shop

From Harry Potter Wiki

Scrivenshaft's Quill Shop is a common supply store in Hogsmeade. It sells various quills, parchment and stationery needed for students at Hogwarts. The shop stock includes stationery such as rainbow ink and extra-large quills. However, students usually prefer to visit Zonko's or Weasleys' Wizard Wheezes when it comes to buying special quills such as joke quills and sugar quills. Scrivenshaft's is visited by Hermione on at least one occasion when she wants to purchase a new quill.
