This is a wökyis M5 Mac mini docking station with a built-in monitor. I purchased an extra one as a gift, but it's no longer needed, so I'm selling it unopened. It's currently available on the direct sales site with an early bird discount for $169.99 (plus $20 for shipping options), which is approximately 28,000 yen. I'm already using one myself, and it's very good. The 5-inch LCD is best used for specific purposes. There's also an m.2 SSD slot on the back. You might be concerned about heat dissipation, but the cover part is metal and acts as a heat sink. The magnetic attachment is also good. Please note that this is a crowdfunding product from overseas, and since it's unopened, you will be responsible for handling any initial defects. Also, please refrain from returns due to minor scratches or dents on the outer box during shipping (I am selling it with the understanding that there may be some).
