Commodore 128 System Guide, Intro Guide Good Condition, with some marks and wear

Description

Commodore 128 System Guide and Intro Guide.
This action is for:
1 Commodore 128 System Guide
1 Commodore 128 Introductory Guide
Items are in Good condition, but do have some age/shelf wear and marks / stains on covers as shown in pics .  I did not see writing from a cursory flip through.   Items are usable, and generally in good shape, but not "very good" or "clean", just used with age, some minor yellowing on edges and some marks / stains on outside covers.
Please notify me immediately of any issues upon arrival, so we can resolve them before you leave feedback. Upon receiving good feedback, I will assume the auction is complete and will give feedback. (I believe the buyer determines the auction is completed to their satisfaction by leaving positive feedback). I want to work to fix any issues, and for buyers to be satisfied with their purchase.
All my auctions are pre-packed and ready to ship, mostly using USPS fixed size/rate boxes, so I cannot combine shipping  Buyers may be restricted to bidding on / buying one item every 2 weeks.
THANK YOU!
