"2025 University Entrance Common Test Past Papers Review: Biology Basics/Biology" Kawai Publishing Editorial Department I purchased this for exam preparation, but I never used it, so the condition is very good. There are no stains or folds on the pages. When shipping, I will wrap the corners with bubble wrap, take additional waterproof measures, and carefully package it in an envelope. Please rest assured. Please feel free to ask if you have any questions. #KawaiPublishingEditorialDepartment #Books #Nature/Biology
