Popular children's picture books depicting adventure and friendship. Set of 2 books ☆ The Mysterious Spy and 100 Roses ☆ Treasure Get! Great Operation Author: Yutaka Hara My child loves these and collected the series, but they seem to have outgrown them recently and no longer read them, so I'm offering them for sale. The smaller one was obtained at McDonald's and is light and easy to carry. It's in color, so I think young children will enjoy it. Both books have no covers. Please understand that these are used items. No price reduction.
