This vintage box with lid is a rare find, made from milk-based plastic or Casein Plastic. The handcrafted piece has a unique texture and design, perfect for collectors of vintage and retro items. The box is made of high-quality plastic material and its country of origin is unknown. It is a perfect addition to any collection of plastic or vintage items. The plastic was originally clear with shards of colored plastic inside. I am not 100% this is Casein but guessing so due to the strong soured milk odor. The overall dimensions with lid are 7 inches long, 5 inches wide and 4-1/2 inches high to the topp of the knob/finial on the lid.
