Can you sell a VR?

Excuse me, could you clarify something for me? I came across a mention of selling a VR, but I'm a bit confused. Are you referring to selling a virtual reality headset or some other type of VR technology? If it's the former, I'm interested to know if it's a new or used product, and if there are any specific features or brands you're considering. Also, would this sale be conducted through a dedicated platform or is there a more informal process in place? I'd appreciate any clarification you can provide on this matter.
