To use these keychains, simply attach them to your keyring, backpack, or any bag using the hand strap. They're great for adding a cute touch to your belongings. Since the styles are randomly selected at dispatch, if you have a specific character in mind, it's best to add a note in your order. Each keychain is sold separately. Keep them away from sharp objects to avoid damage. If they get dirty, you can gently wipe them with a soft, dry cloth. These keychains are suitable for kids aged 4 and up, so make sure younger children use them under adult supervision.
