Lot of 9 +1 books for Leap Frog Tag Learning System.  None of these books has any writing inside, or any ripped or torn pages.  Some have light to moderate or moderate to heavy markings from the Tag pen.  Although the pen doesn't actually write, it does have a tip, and if it is moved with a little (or a lot) of force across the page, it will show marks.  Description as follows:

Tinker Bell's True Talent (Age 5-7)-  Book has light marks from Tag pen on the cover.  Book has only very light markings inside from the Tag pen.

The Cat in the Hat by Dr. Seuss (Age 4-7)- Book has moderate marking on the cover from the Tag pen, but very little marking inside.

Fancy Nancy Explorer Extraordinaire! (Age 5-7)- Book has only very light Tag pen marking on the cover, and very few marks inside.

Star Wars The Clone Wars "Rescue in the Sky" (Age 5-7)- Book has light Tag pen marking on the cover, but almost none (if any) inside. 

T. Rex's Might Roar (Age 4-6)- Book has very little Tag pen marks on the front, and almost none (if any) inside.

Kai-lan's Super Sleepover (Age 4-6)- Book has heavy Tag pen marking on the cover, but only very light marking inside.

Scooby-Doo! Shiny Spooky Knights (Age 5-7)- Book has very light to moderate Tag pen marking on the cover, but very little inside.  There is one spot on p.26-27 where the pages got stuck together, and these is minor damage (however, it's on a picture and not on the words, so it doesn't affect the reading).

SpongeBob Squarepants The Tour de Bikini Bottom (Age5-7)- Book has light to lightly moderate Tag pen markings on the cover and inside.

Scholastic I Spy Imagine That! (Age 4-6)- Book has heavy Tag pen markings on the cover, and moderate markings inside.

+1 Bonus Mini book- Let's Play Tag! (Age 4-8)- This is a thin paperback book...more of a demonstration type book. Includes different characters and activities on each page.  This is not one of the 9 books listed, just a bonus that I'm including.
