The RayNeo Air3S is smart glasses that offer a next-generation AR experience. - Model Name: RayNeo Air3S - Brand: RayNeo - Accessories: All included - Connection Type: USB-C Thank you for viewing. I purchased these six months ago and used them a few times (less than 10 times). They didn't suit me, so I'm selling them. They function perfectly and are in excellent condition. The condition is relatively clean, but please understand that they are used. Feel free to negotiate the price.
