Bluetooth-connected touchpad with operation buttons, very convenient. Powered by two AAA batteries. ↓ Please check the details here https://mco.jp/products_pc/ttp-bt01/ I used it for a while after purchasing it, but it didn't suit my usage style, so I'm selling it. It's been 2-3 years since I bought it, and I've only used it for a few months. There are no noticeable scratches, but there are some scuff marks, so please check the images. Also, the power ON/OFF switch on the back is a bit stiff. I used it with a Windows 10 PC, and multi-gesture operations work without any problems. Those who are used to two-finger, three-finger, and four-finger taps and swipes will find it easier to operate than a laptop touchpad because of the larger operating surface. I checked the operation before listing it, and it worked without any problems. Thank you for your consideration.
