Type of goods: DVD Character: Shimajiro This is a DVD set from Shinkenzemi Kodomo Challenge. It includes monthly DVDs from the age of 4 (March) to the age of 6 (December). I have checked that they work. However, I haven't watched all of them from beginning to end. Please be aware of this. I think this is a good educational material to prepare children for elementary school, starting from the age of 6. It comes with a special, not-for-sale case!
