This is a VIVE PRO EYE full set, originally priced at 190,000 yen. It worked without any issues in VRCHAT. It was used for about 2 months. There are no problems with the sound, tracking, button feel of the controllers, or the use of eye tracking. All accessories are included. Since it has only been used for a short time, the product looks to be in good condition. Because it's optical, you can use full body tracking and face tracking by using a face tracker. I have a Quest 3, but this product fits me better and the image quality is quite good, so I recommend it. Full body tracking is easier than on the Quest. I'll offer a slight discount if you purchase trackers with it. Feel free to ask any questions.
