Is it Bakelite?

This is one of our finds from the resale shop down the street from our house.

I found it at the bottom of a box, and loved the clasp. This is the way it works: you lift up the piece at the center, and then each horizontal piece folds open at the middle point so that the opening forms a rectangle.

The incised lines and ivory color make it look like scrimshaw, but I doubt that it actually is ivory. Do you think that it's Bakelite? Any guesses about when or where it might have been made? Nothing inside to identify the bag, and the hardware seems to be handstitched to the cloth part.
