These Christian books are great for personal study or adding to your collection. To use them, simply open the pages and start reading. When handling, try to keep your hands clean to avoid staining the pages. Store them in a dry and cool place to prevent further tanning or damage from humidity. If you notice any loose pages, you can use a little glue to fix them gently. Be careful with the 'Sex' book's dust jacket as it already has some wear; avoid rough handling to prevent more tears.
