Check out eBay 262677957176. The carving is different but the color is close. The seller says they are Celluloid beads.

In thinking about Celluloid as a possibility, I noted that camphor is actually used in cooking in India. So could the odor of celluloid possibly remind you of mild curry?

If you can get your hands on a white celluloid ping pong ball - they should be cheap enough - you can puncture the ball or otherwise abrade it to get a sample odor of camphor as it's found in celluloid plastic.

Good luck!
