The natural wood Smart Book Light collection is certainly a great additional piece of art to any home.

The beautiful, exquisite design opens to a full 360 degrees with cleverly concealed magnets. The lovely soft touch Tyvek pages are tearproof and water-resistant and are lit by long-lasting LED lights and encased by the stylish laser-cut wooden cover in your choice of maple or walnut.
