Revised edition of Basic Biology, ideal for exam preparation. - Title: Basic Biology Revised Edition - Author: Yamaguchi - Publisher: Gakken - Price: 1,650 yen - Series: Sosei Series I checked the contents for about a minute, and it appears there are no markings. However, there may be oversights, and there might be some scribbles or spiral binding. Please refrain from purchasing if you are sensitive to these issues or are looking for a perfect copy. (Some items may have minor scribbles.) Please judge the condition of the product based on the photos and purchase with your understanding. If there are any scribbles that significantly hinder your study after purchase, please contact me without confirming receipt upon arrival. I will cover the return shipping costs if you contact me within two days of arrival. Please purchase only if you understand that this is a used item. I am also listing multiple reference books. I will offer a 100 yen discount for combined purchases, so please feel free to ask. (Combined shipping may not be possible due to shipping costs.) Thank you.
