The diameter of the buckle (including frame) is 2.5cm / sold as a single piece The metal frame part is not afraid of contact with water and will not rust The pattern is handmade embroidery and non-electric embroidery After I designed the artwork myself, I stabbed it with one stitch and one thread ❤ So each pattern will be a little different :) Allows you to sew the cute bag button on anything you like ~ It can be sewn on the collar, sleeves, bags, coats and hats!
