Thank you for viewing my items. The size is approximately 4cm wide. If there are no comments, 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 with care, 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. I am also selling on other sites, so items may be removed without notice. Thank you for your understanding. Thank you for your interest.
