This ear cuff is so cute with its aquamarine blue and silver color! It's a great deal as a set of 2. It uses a 5cm wire (9-pin), and the diameter is about 2cm (*^▽^*). The wire is stiff enough to be adjusted with your fingers, so please try adjusting it♪ It's praised for being comfortable to wear, and there are many repeat customers. Also, because it is a handmade product, there may be some imperfections... Please understand this beforehand m(._.)m For those who want to purchase it a little cheaper, it can be discounted by 100 yen if you choose regular mail. However, regular mail takes about a week to arrive, and there is no compensation if the package is lost during delivery due to a postal accident. Even if it doesn't arrive, you will still be asked to rate the product. If you are okay with this, please contact us via the comment section before ordering. m(__)m Please note that we cannot change the price or shipping method after you have placed your order.
