Exquisite 19th century Ivory and tortoise match safe nude woman

An Exquisite 19th century German match safe made of Ivory and what we believe is tortoise shell. It bears an inscription which reads “du sollst Nichttohen”. I don;t read German but the detail of the inlay in remarkable. Ther are some minute losses but by and large this is an extraordinary example of a match safe.
Some losses to the ivory and tortoise shell.
