Thank you for viewing my items from among many others. The size is approximately 3.5cm 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 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 comments 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 very much.
