The Card Captor Sakura clow card set contains all 52 clow cards,
and comes in a very nice clow card book.
The book is a hard cover book, even though it's more accurate to say it's
a box. Inside this book is a smaller box containing the 52 clow cards.
This inner box is not needed, as one can put the clow cards in the
clow card book itself. It's probably there for protection of the cards.
Each clow card is made of sturdy cardboard, and is probably "actual" size.
It doesn't have Sakura's, or anybody's, name on it. (^_^)
The pictures on the cards are probably a little different from the
manga or the TV.
