OPPAI ZUKAN :: Ecstasy 原寸大おっぱい図鑑 The Actual size boobs book full-scale visual dictionary [PHOTO BOOK - JAPANESE EDITION] Tankobon Softcover – January 1, 2017

This visual guide to anatomy is a very special find. Its level of detail and design is incomparable to other visual dictionaries to be sure. I am astounded that it really comes in a size that affirms the description of being life-size representations of the focused anatomy. I do wish it were a hardcover, but it doesn't impede the book for me. This book is an enjoyable read with a lot of re-readability, and is also probably a fun gift idea for a friend with peculiar interests.
