I bought this with the intention to use it as a reference book.
It's full of images and covers a general idea regarding the different wrinkles and folding base of the clothing texture etc.
The book is in japanese but it's okay since all you have to do is observe the images.
Useful for those who want to improve drawing clothes.

Love it! They fit nicely and as the description says you get random designs, you won't be disappointed since all are so adorable. I'm glad I bought these considering it was my first time ordering online.
