Art Deco/mod black and ivory vintage oval bangle

This bangle bracelet is a vintage piece in a unique oval shape. It can go Art Deco or Mod, dress it up or down! It is made of vintage thermoplastic, has some weight to it, and no molding seams but I am hesitant to confirm the material. The ivory color is a result of yellowing, as genuine phenol formaldehyde resin does, but I haven’t seen one that has remained this pale. Tested negative with 409 swab. Still, a well crafted lovely true vintage piece. Measures 7 and 1/4 in circumference. Enjoy! 😊
