This is a set of Unit 4 from the English learning material, GrapeSEED. Almost unused. CD (stored on the inside of the booklet's front cover) DVD (unopened) I have many other units besides this one, and I plan to list them sequentially. If you have a unit you're looking for, please let me know and I'll check if I have it. If you purchase two units together, I will discount the price by 200 yen. (Purchasing more than that may result in higher shipping costs) GrapeSEED English * GrapeSEED is used in 18 countries around the world, and over 70,000 children are learning with it in approximately 900 schools.
