Survival Series "Survival at the Natural History Museum" 1 & 2 Set. - Title: Survival at the Natural History Museum 1 - Title: Survival at the Natural History Museum 2 - Price: 1,200 yen each + tax There is some wear and tear on the covers, etc., but I don't think it's anything to worry about (see photos). Compared to others in the series, these books are thicker and heavier, giving the impression that they are packed with content (both volumes 1 and 2). For a set of two books, the weight exceeds the maximum 1kg for "Nekopos," so they will be shipped via "Yuyu Mercari Bin (Yuu-packet Post)."
