This is the E-pencil for Kumon English materials. Operation has been confirmed. It is compatible with English learning materials. An SD card is required for use with other languages. The main body appears to be in good condition, but the bag has a name written on it and is slightly dirty. Please check the photos for the condition, and refrain from purchasing if you are concerned about minor details. *Batteries (AAA) are not included, so please prepare them. I am unable to respond to messages requesting price reductions, individual sales, or combined shipping, so I will delete them. I would appreciate it if those who understand that this is a used item would purchase it! Thank you very much!
