This superbly carved box is conceived in the shape of two interlocking rings, symbolising completeness, a motif that acquired popularity during the Ming and Qing dynasties due to its auspiciousness. Bamboo-veneer boxes of this form were held in high esteem and produced for the Imperial Court. For another conjoined circular box of identical size and form from the Qing Court collection, preserved in the Palace Museum, Beijing, with an additional tier and carved with clouds, see Small Refined Articles of the Study.
