Invisible steel book holder
The book holder Conceal by umbra becomes virtually invisible behind a stack of books. Your books thus seem to float along the wall by magic.
Simply insert the spine of the lowest book into the Conceal -holder and you can stack up to ten more books on it...
Conceal is easy to mount on the wall and is made of powder-coated steel. The book holder is available in two different sizes - for large and small books.
