Using this brooch is super easy. First, get your Precure Ribbon and attach it to the brooch. Then, give the heart - shaped mirror ball a spin, and just like magic, you'll transform into Cure Idol. If you want to be Cure Wink or Cure Kyun Kyun, simply change the ribbon. After transforming, place the brooch and ribbon on your chest to show off your Cure. As for maintenance, keep it away from water and don't expose it to extreme heat or cold. When not in use, store it in a safe place to avoid scratches. Also, make sure the ribbons are clean and in good condition for the best transformation experience.
