To use these Betty butterfly mini ponies, simply pick up a lock of hair and wrap the elastic around it. They're great for adding a bit of sparkle to everyday looks or special occasions. As for maintenance, keep them away from sharp objects to avoid tearing the fabrics. If they get dirty, you can gently wipe them with a damp cloth. Just don't soak them in water as it might damage the glitter and fabric. Have fun styling with these cute ponies!
