Using this Harry Potter letter writing set is easy. First, take out the gold feather pen. Dip it in ink if needed, then write your letter on one of the provided letter sheets. You can use the stickers from the sticker sheet to decorate your letter. Once you're done writing, put the letter into one of the envelopes. For the pen, make sure to clean it after use to keep it in good condition. Store the set in a dry place to prevent the paper from getting wet or damaged.
