This is a rare monitor-integrated mechanical keyboard. I purchased it on Amazon for around 45,000 yen. It is currently being sold for 39,999 yen. https://amzn.asia/d/4sjkcWq It connects with a single USB-C cable and is a multi-functional and convenient keyboard with an M.2 SSD slot and USB hub functionality. It's mechanical, and the key touch feels similar to high-end keyboards. It is described as having yellow switches. I bought it because I was using a desktop machine, but I quickly switched to a laptop and didn't use it much, so it ended up being stored away. I'm selling it at a low price, so please consider it if you'd like to try it out. *Price negotiations are welcome, so please register your desired price from the "いいね" (like) button. I will make changes if it's acceptable. Please note that shipments for payments made on or after the morning of October 24th will be after the 30th.
