BookNudge – Rosewood Book Aligner with Vinyl Wood Accent (2.5" or 3" Depth) For the detail obsessed shelf stylist and bookish perfectionist, the BookNudge brings order to your stacks in the most satisfying way. Just slide it up to your row of books. It gently nudges the spines into a uniform line, using the edge of the shelf to set a consistent depth. Available in two sizes (2.5" and 3") to match the look and feel you want for your shelf styling. Each BookNudge is 3D printed in rosewood textured PLA and finished with our signature vinyl wood accent. The bottom is felted to glide smoothly while protecting your shelves. Currently available in Rosewood only. More colors coming soon. Made for readers, perfectionists, and the book witches who believe every shelf tells a story and every spine should sit just right. This is a wonderful tool for OCD people (like me). I rearrange my shelves almost daily and this helps keep my books in line across the shelf. I LOVE IT!!!!
