I made twin ribbons for kids using beautiful light blue ribbon (*^^*) I think they are the perfect size for twins for toddlers to lower elementary school children. Perfect for everyday use or as a gift (*^^*) Size: Approximately 5.5cm x 4cm Uses thin rubber bands Please purchase only if you understand that these are handmade. They are not as strong as mass-produced items. They will last longer if you tie them with another rubber band first, and then use them as decorative rubber bands.
