This is the Kumon English listening device, the e-pencil. Purchased in August 2017, and used for about a year. I think it's in good condition. SD card is not included. New batteries will be included. I am also selling an e-pencil adapter and textbooks. I have confirmed that it works with the textbooks. It is possible to combine shipping, so if you let me know before you purchase, I will combine them. (Please note that if someone else purchases them before I can check, I apologize.) I handled it with care, so I think it can still be used for a long time.
