a small rip (less than 1 inch) in the cover is OKAY-
so if the top of the back cover has the left corner cut off at a diagonal- 1" x 1/2"- that would still be postable, correct?
That is fine Adrienne. Some used book stores do that. The book is still postable.
As long as the amount missing is less than 1 square inch they are fine, so your sounds perfectly postable.
Thank you for your patience
