Using this Harry Potter stationery set is a breeze. You can use the pen to write down your thoughts, stories, or notes in the notebook. Just hold the pen like you would a regular one and start writing. When it comes to the notebook, you can use it for school, work, or just for personal journaling. To take care of this set, keep the pen capped when not in use to prevent the ink from drying out. For the notebook, avoid getting it wet as it may damage the paper and the Hedwig plush on the cover. If the pen runs out of ink, you might need to replace it with a compatible refill. Overall, this set is a great addition to any Harry Potter fan's collection and can last a long time with proper care.
