Invisible Bookend by Paul Cocksedge
Designed by Paul Cocksedge, this bookend is so minimalist, you can’t even see it. It is lightweight, suitable for desks, shelves, or any flat surfaces, and can easily hold more than a metre and a half’s length of books, of all shapes and sizes. It seems to be non-existent, yet it will make you look twice, and that is the beauty of it.
If such design inspires you, you will also like the Conceal Book Shelf by Umbra.
