Wooden & horn bone inlay bangle BRACELET (read disclaimer), vintage

Disclaimer: when this bracelet was acquired I was told this was wood and bone / horn inlay. I can’t verify this though so for all I know, it’s another material but it does look more organic than plastic (my opinion). See photos and video for details, condition and measurements.
