To illiterate folks like ourselves it also looks just like any box used to pack and present ceramics, glass or any other artesan made item or kimono accessory.

I think in this case what makes the box special is the writing on it that I assume says something along the lines of "Umbilical Cord Box" and the fact that it is made of paulownia (kiri) wood - helps protect the yummy, yummy contents resist the appetite of many generations of intrepid insects.
