Using the Doodletop is super easy. Just give it a good spin and start doodling as it moves around. When you want a different color, simply pop out the pen and swap it with another one. It's a great way to keep kids entertained and creative. As for the pens, don't try to force them out too hard as it might damage the pen or the top. Keep the Doodletop away from water as it can ruin the ink in the pens. Also, store it in a dry place when not in use. This will help the pens last longer and keep your Doodletop in good condition. Have fun creating your masterpieces!
