These beautiful storage boxes are called Inka. On the outside, they resemble ordinary books, but when you open them, you will find absolutely nothing. They are completely empty, so you can use them to store all of your small items. Inka is sold in an assortment of two designs. Extremely beautiful by themselves, Inka can also easily blend into your bookcase. The box measures 16 cm in length, 7 cm in width and 22 cm in height.
