Hi guys. New to the forums. I recently purchased a used Nexus 10 from Craigslist for $260. It came with the oem book cover in red. However, I find that the cover doesn't stay shut while travelling so it keeps waking my screen. I've purchased a folio case with a smart cover and now I realize I don't have the plastic cover to reinstall once I remove the book cover. Any suggestions would be appreciated. I've tried Ebay & Amazon but no luck. Thanks!
