Up to 1,000 officially licensed products are to be produced for next year's Summer World University Games in Chengdu, Chinese organisers have announced.
A panda called Rongbao was last month revealed as the mascot for Chengdu 2021.
More than 100 retailers will open across China, stocking official merchandise, with the Games due to open on August 8 next year and conclude on August 19.
It is expected that, as Chengdu is the capital of south-western China's Sichuan province and is known as the home of the giant panda, many of the products will feature the animal.
Among non-panda related items already on sale are limited editions of badges featuring the official Chengdu 2021 logo.
Limited edition badges of 21 pieces of pure gold, 105 pieces of pure silver and 1,895 pieces of pure copper have been sealed in 2,021 uniformly packed boxes and sold at random.
Each one will cost only CNY100 (£11/$14.50/€13), even though the three gram pure gold one is worth is CNY1,699 (£188/$245/€220).
The eight gram pure silver one is worth CNY399 (£44/$57/€52).
