• Apple does not make a “pen” product. They do make Apple Pencils to use with iPads.
• “when we opened the box we realised there is no extra pin tip in the box.”
  • If you purchased an Apple Pencil, it would be in its own box.
  • There is no instance where any additional product is packaged in an iPad box.
• Apple Pencil is not sold with an extra tip.
