This is a used Oculus Rift CV1 (first-generation Oculus Rift). It's a VR HMD that uses a stand-type sensor placed on a desk or similar surface. 【Operation】 I haven't been able to confirm its operation recently, but it was working without problems about two years ago. It is being sold as-is, and I cannot guarantee full functionality, so please purchase only if you understand this. It hasn't been used very often. The main unit is in quite good condition. 【Appearance and Accessories Condition】 There are some marks from removing stickers on the main unit and accessories. As it is a used item, there may be some minor dirt or scratches on the box. Please refrain from purchasing if you are particular about the condition or are looking for a complete product. 【Other】 Please consider this item with the understanding that it is a used and long-term stored item. If you have any concerns, please ask questions in the comments before purchasing.
