Thank you for viewing my items. The size is about 3cm wide. If there are no comments, I will make it with a hair tie. If you would like a pony hook or brooch, please leave a comment. The price remains the same. The hair tie rubber band can be replaced. You can replace it by threading and tying a rubber band that is not looped. I make each item carefully, but as these are handmade, please understand that there may be imperfections (such as air bubbles). If you purchase two or more items, you will receive a 50 yen discount. Please let me know the numbers of the items you would like to purchase together in the comment section. I will create a combined listing for you. I am also selling on other sites, so I may delete items without notice. Thank you for your understanding. Thank you for your consideration.
