One size fits all. It’s true. This eBook Reader case holds the Amazon Kindle, the Barnes&Noble nook, and all sizes of Sony eBook readers. And it holds them safely with the super-secure 3M™ Dual Lock™ lock-in system, which offers four times the strength of Velcro® and an almost infinite lifetime hold. Don’t worry, there’s no sticky residue when you remove it. Not only that, this case looks and feels fantastic.
