※ Please understand that the batteries will be removed before shipping. The appearance has scratches and dirt, but it worked as a calculator. I have only confirmed that it works as a calculator with batteries inserted. I have not confirmed it by connecting it to a computer, so it is untested and will be sold as a defective item. If you understand that this is a defective item and are willing to purchase it after carefully reviewing the product page and images, please consider purchasing. It will be placed in a bag, wrapped in bubble wrap, cushioned with newspaper, and shipped via Yu-Packet Plus dedicated box from the post office using Yu-Yu Mercari service (please understand that the batteries will be removed before shipping). We would appreciate it if you could read the profile before considering a purchase. We do not negotiate prices. We look forward to your purchase. Thank you for reading to the end. #DefectiveItem #CANON #KS1200TKM #Calculator #Canon #Trackball #USB
