Product Details: Official Crypton / Hatsune Miku product Handmade Material: 925 Sterling Silver Colour: Silver A must-have for any Hatsune Miku fan Hatsune Miku is a Japanese music sensation, a 16-year-old blue-haired girl with a unique voice and prodigious energy. What makes her special is that she is not a human singer, but a virtual persona who uses a computer-generated voice and 3D graphics to perform on stage. With a repertoire entirely provided by individual creators, she is the first truly crowd-created virtual talent. But being virtual doesn't stop her from filling up concert halls, or teaming up with major artists like Lady Gaga and Pharrell Williams!
