Thank you for viewing! This is a set of 8 flower hair ties! Regarding these hair ties, if the elastic breaks, you can use your own elastic to replace it. These are recommended for those who want something cute, but whose kindergartens don't allow vinyl elastics! If you are looking for cute hair ties, you can purchase them from just one piece, so please try them out. They are also recommended for matching with friends or siblings! The elastic size is 2cm. The charm sizes vary, so please check the photos. They are about 2cm in size, similar to the elastic. *Please note that because we use overseas-made parts, there may be some minor scratches or color unevenness. Thank you for your understanding.
