Thank you for viewing! These hair ties can be used by adults, babies, and kids! The rubber band can be replaced if it breaks. These simple and cute hair ties are recommended for friends and sisters to wear in different colors or matching sets ⭐︎ (Because they are handmade, I cannot make exact duplicates.) Please consult with me in the comments! Due to being handmade, there may be some air bubbles, burrs, unevenness, bumps, or dust. Also, they are not as strong as mass-produced products.
