Portable screens for your laptop. I've used these maybe twice. They are practically new and still in the original box with original packaging. I used them with my Macbook Pro 14" computer. They have multiple attachments though. You can use them with screens ranging from 12-20 inches. Here is a link to a description on their website: https://www.thexebec.com/products/xebec-tri-screen-2. I bought these in 2021 during the COVID shutdown. I don't really need them much anymore with my desktop monitors. I originally paid the $499. Included in the box: Xebec Tri-Screen 2 2 x USB-C to USB-C 90 Degree Cables 2 x USB-A to USB-C Adapters 1 x USB-C Extension Cable 2 x Mini-HDMI to HDMI Cables USB-C 90-Degree Pass-Through Charging Adapter
