Logitech Keyboard and Mouse Set ※Mouse is missing, so it's not included in the sale. String: Hangul I bought this 5-6 years ago when I was studying Korean. I haven't used it frequently. It's been used indoors, so I think the condition is good. I don't have a device to test it, so I haven't confirmed the operation. ※Will check later. The batteries are still in it, and it turns on. No instruction manual. Please research it yourself. It's been stored at home, so please refrain from purchasing if you are concerned. Logicool Logitech
