Compare with a very similar bamboo veneer box in the form of a finger citron included in the University Museum and Art Gallery, The University of Hong Kong exhibition Ming and Qing Bamboo, 2000, illustrated by S. Kwan, Catalogue, pl. 85 where the author notes that the box is likely to have been a work of the Imperial workshops during the Yongzheng or early Qianlong period and that bamboo veneer, tie huang pieces were not available outside the court until the early 20th century.

A pomegranate-shaped box in the Palace Museum collection, Beijing, attributed to the Jianing workshops, was included in the Royal Academy of Arts exhibition, China: The Three Emperors, London, 2006 and was illustrated in the catalogue, no. 288.

The tie huang technique involved removing the yellow inner skin of the bamboo skin which was soaked and then formed into layers that were adhered to a bamboo or wooden core.
