Using these 6 - click multicolored unicorn pens is super easy. Just click the top of the pen to switch between the six colors: blue, green, yellow, red, purple, and black. When you're buying, remember to leave a note at checkout to get the pen style you want. If you don't, you'll get a random one. To keep your pens in good shape, don't expose them to extreme heat or cold. Also, try not to drop them as it might damage the ink flow. When not in use, keep them in a dry place. Enjoy writing with these fun pens and make your notes colorful!
