This is a book by Yukihisa Oikawa, "The Switch: The World's Easiest Guide to Using the Subconscious Mind," which is a book that will be beneficial for your life. I purchased it two months ago, and while there are no stains, a small part of the upper right corner is slightly peeled (see image 4), so I've marked it as having some scratches and stains. If you don't mind this, please consider purchasing. - Title: The Switch - Author: Yukihisa Oikawa - Genre: Business & Economics - Feature: How to use the "Subconscious Mind" - Bonus: Amazon Category #1 There are no smokers in my family, but I do have a cat.
