These books are great for learning about Tropical Africa. To use them, simply open the pages and start reading. When handling the books, be gentle because the bindings are a bit loose. To maintain them, keep them in a dry place away from direct sunlight. Avoid getting the pages wet or dirty. If you need to clean the covers, use a soft, dry cloth. And when you're done reading, store them on a bookshelf to keep them in good shape.
