The Dong Son Fine Arts Joint Stock Company started the project in March 2010. The dragons, each weighing between 3-3.5 kg, will be numbered and come with a certificate of origin and the official logo of the grand celebration of the 1,000^th anniversary of Thang Long-Hanoi. The dragon design, modelled on the typical style of the Ly dynasty, has been registered by the company for copyright. 

The dragons numbered 001 and 1,000 will be auctioned to raise funds for the Thang Long Culture Fund, which will be used to restore the city’s non-intangible cultural heritages.

Other dragons will be sold as souvenirs at the website http://www.rongthanglong.vn.
