Paperback. They are used, but in good condition. I got the entire set for my birthday a couple years ago..over70 of them. Some have writing on the inside cover..but other than that....they have a lot of good reads left in them.
Well i have a ton of goosebumps books, and while some look like theyre new, others have just a bit of marking on the inside cover, but not on the actual page. So for these im not really sure but when i looked at them they looked alright. Now ive had these about 2 years so the covers are just a bit worn but nothing really noticable :)
