WARNING: These teachings are TOXIC. Make sure that you don't inadvertently endorse books on your shelf you've kept just for research purposes! These stickers are designed to fold over the spine so that there is a warning both on the front of the cover as well as a visible warning on the spine while they rest in your bookshelf.

Care instructions
- Use a soft, clean and dry cloth to gently brush any dust or dirt off from the center of the sticker outwards.
