These are trackers for full body tracking in VRchat and other platforms. Used for less than a year. The troublesome assembly and wiring are already done, so I think you can put them on quite smoothly. I've also put on easy-to-understand stickers. The official assembly video is on YouTube, so there shouldn't be any problems even if the stickers come off. - Model Name: HARITORA X 1.1B - Accessories: Straps, sensors - Condition: Almost unused (I think less than 50 hours) Thank you for looking.
