Thank you for viewing! This is an English learning material from Yamaha. It includes 4 DVDs and 4 CDs. Operation has been confirmed! My child used these when they were around 2 to 6 years old. I believe the current Yamaha materials may have changed, but these are good for getting familiar with English listening at home! Retail price: 25,400 yen The items appear relatively clean, but some cases have minor peeling. See image 5. DVDs 2 do not have lyric cards. See image 3. Please understand that these are used items. Shipping may be changed to Yu-Yu Mercari delivery. Thank you very much. m(__)m
