Important note on all our listings: we make no guarantees as to whether these graded books have Newton rings or not. Newton rings are harmless phenomena that sometimes happen when two different types of plastic are next to each other. They are not water or oil damage. Please review all images carefully. We will not accept returns due to Newton Rings. More information here at CGC's site: https://www.cgccomics.com/boards/topic/440951-newton-rings/
