Turned of wood this black vase has what appears to be a prominent egg residing within. Removing the egg one finds it to be the top of the vase and underneath is seen an egg with black rim as in the shell in a ball and vase effect. Taking away this piece one will find another white egg that divides in have to reveal yet another egg but of a different color. Opening the different color egg you may keep going many times through many eggs until you reach the smallest which is almost pea size.
The nest of eggs don't close very well but the egg lid and egg shell with rim work well. Condition very fine.
