This is a set of two study books for the 2025 edition of Business Practical Law, Level 3. I also purchased these and passed the exam by studying only these two books. I don't think there are any major stains, but I haven't checked every page thoroughly, so there may be some dirt or folds. Please understand that these are used items before purchasing. The official Know-How app was already registered when I purchased the books and couldn't be used, so I studied only with these books. Shipping will be via Nekopos.
