Judy: The corrugated paper make a very nice package. It's easy to make and as a result it is also strong and pretty damage proof. The customers love it - it looks so professional. The best part is that it is inexpensive. And if you have any left over it's great for school science projects. .
Once wrapped you end up with a flat portion on either edge of the book (Where you staple/tape) and then a "lump" all nice and smooth and even where the book is. Making the book securely wrapped and not adding a great deal to weight.
