Air guns have been offered for sale in Ho Chi Minh City and other localities despite the fact that purchasing and owning the items are banned in Vietnam.
The guns are manually made by individuals, mainly for hunting, and cost an average of VND200,000 (US$9) to VND1 million ($46) each, depending on the materials used in the guns.
Some home-made air guns are even sold for around VND10 million ($460).
