Thank you for viewing my items from among many others. The size is about 4.5cm wide. If there is no comment, it will be made 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 they are handmade, please understand that there may be imperfections (such as air bubbles). You will receive a 50 yen discount when purchasing two or more items. 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 items may be removed without notice as they are also listed on other sites. Thank you for your understanding.
