We know that every finger is different than another. We normally do our rings in sizes between 9 and 11. They are adaptable so you can use it if you are in 9 or 10 or 10-11 size. If you want the rings in other size, please indicate it when you buy it. So this mean that you can buy any ring of the shop and change the size after purchasing. Please note that we need to do the ring again and this takes about three days.
