I have 2 hardback copies of Surgical Technology for the surgical tech. A positive care approach. 3rd edition, one still has the soft ware inside. I also have a paperback copy of the same book. and one study guide and lab manual for these books. All of these are in excellent condition. The study guide does have some ink writing in the first 3 pages. After page 6 not a mark. The Intro to Algebra is in good shape, the pages inside are immaculate, the cover has a little wear. the writing reference books are in fairly good condition. One has some water marks but are still completely readable and useful.
