lacquer tray

DIA115xH65mm, Thailand

This curious circular lacquer tray has been a puzzle for me, I cannot figure out what was the original usage for such item.  The material of the tray is very delicate, made with paper and a semi transparent lacquer.

If anyone know of the origin and usage of this tray, please let me know!
Other unsolved mystery.

This is going to be my next Something Old Something New project, stay tune!
