Thank you for viewing my items from among many others. The size is about 3cm wide. If there is no comment, I will make it with a hair tie. If you would like a pony hook or brooch, please leave a comment. The price does not change. 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 they 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. Please note that I may delete items without notice, as I am also selling on other sites. Thank you for your understanding. Thank you very much.
