Material Casein formaldehyde
Casein formaldehyde is a plastic of natural protein origin, made from organic substances such as milk, horn or vegetable products such as soy beans, wheat, etc.

It can be made to look like celluloid, ivory, or artificial horn.
It is odourless, insoluble in water, and only with difficulty inflammable.

In the first decades of this century, casein formaldehyde was used to make buttons, pins, cigarette-cases, fountain pens, umbrella handles and radio cabinets.
