The Flexilight is an indispensable—and super portable—tool for late-night readers! The sturdy clip attaches to the back cover of your book, allowing for easy page-turning. The flexible neck enables perfect positioning while the bulb illuminates your page with eight lumens of bright light. When not in use, the ultrathin 5½"-tall reading accessory slips right between the pages to become a bookmark. Choose from three fun patterns: Green Dots, Orange Geometrical, or White Flowers. Requires two CR2016 lithium batteries (included).
