These ear cuffs are adorable with their green and white color scheme! This is a set of 2, and it's a great deal! They use 5cm wire (9-pin), and the diameter is about 2cm (*^▽^*) The wire is stiff enough that you can adjust it with your fingers. Please try adjusting it to your liking♪ They're praised for being comfortable to wear, and we have many repeat customers. Also, because these are handmade items, there may be some imperfections... Please understand this beforehand. m(._.)m For those who want to purchase them a little cheaper, we can offer them for 300 yen if you're okay with regular mail. However, regular mail takes about a week to arrive, and there is no compensation if the package is lost during delivery. Even if it doesn't arrive, you will still be asked to rate the transaction. If you're okay with this, please contact us via the comment section before ordering. Please note that we cannot change the price or shipping method after you place your order.
