Thank you for finding it! This item uses 3.8cm walnut buttons. It comes with a 5cm diameter hair tie, and the back is felted. I embroidered my favorite Maskman and made it into a hair tie. Wear this, get pumped up, and let's go watch some pro wrestling! How about it? [Discounts for multiple purchases!] If you would like to purchase multiple items, please check my profile.
