Using your You & Idol Precure Bracelet Watch and Case Set is super easy. Just put on the bracelet watches like you would any normal bracelet. The lockets can be used to store small keepsakes or just be displayed as part of the collection. When it comes to maintenance, keep the watches and lockets away from water to prevent damage. Use a soft, dry cloth to gently clean them if they get dirty. And remember, since this is a pre - order item, it might take a little time to arrive, so be patient and get ready to enjoy your awesome set!
