This is a benefit sent twice a year to Family Club members. Four books from 2014 to 2017. I have opened the Christmas presents from 2014 and 2017. Please take a look at the photos. You can use them by looking at the picture books while listening to the CD, and checking the guide for any words you don't understand. I think this is perfect educational material for children who have started to understand a little English. Please purchase if you understand that these have been stored at home for a long time.
