Space-saving it's not, but the book hook is a rather more attention-grabbing alternative to the modest bookmark.
"The classic paper stripe as a bookmark has always been a temporary solution for me," said Tell Ritterbach, designer. "Because I like to leave my books open I got the idea of a whole new concept.
"I wanted something better. Something, whose shape similars the shape of the opened book, like a negative to the positive and prevents it from damages. With that the idea of book hook was born. With my first sketches I let it produce as a prototype. After more improvement with regard to the material, angle and edge devolution was a marketable product of high-quality produced."

The book hook is available in beech, birch and oak for 30 euros from Connox.
