Lisam Luft ◼︎ Calculator with Cover ※ Instruction manual included. ※ Please check images 7-9 for size details. ※ Operation confirmed. I am selling this because I stopped using it after buying another calculator. It still works fine, but it has been stored at home, so please purchase only if you understand this. Please refrain from purchasing if you are looking for a perfect item. If you have no questions, you can buy it immediately.
