Using this pen is easy. Just hold it like a regular pen and start writing with the black ink. To have some fun, play with the removable Harry Potter figure on the pen. You can move it up and down or spin it around. When not in use, keep it in a safe place to avoid losing the Harry Potter figure. To maintain the pen, make sure to cap it properly after use to prevent the ink from drying out. Also, avoid dropping the pen as it may damage the moving parts of the Harry Potter figure.
