Vocaloid 3 Hatsune Miku voice synthesis software, with 3 CDs and an installation guide. - Model Name: Vocaloid 3 Hatsune Miku - Accessories: Installation guide, 3 CDs - Software Type: Voice synthesis software - Supported OS: Windows - Character Name: Hatsune Miku Stored in a case in a smoke-free, pet-free home, away from direct sunlight. The contents, including the box, are in very good condition. I am unsure whether the usage code inside has been used. I completely forgot I had this, and I don't remember ever installing or using it. However, I cannot check the code because entering it to verify might render it used. Please understand.
