This is an ear cuff made with 6mm yellow glass beads and pearl beads. It's a great deal with 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 popular 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
