If you're in the market for an old South African flag, be prepared to answer some tough questions before you can buy one.
A flag-manufacturing company in Cape Town that sells newly printed copies of the old South African flag says that although it will not stop selling the flag, it will not sell it to someone who wants it for the wrong reasons.
"There's a still a demand for it, so to put a blanket ban on the flag doesn't make sense," says Andrew Smith, the owner of Flag Kit South Africa.
"And there are some legitimate reasons to produce a flag that is historically accurate, so for us to not sell it doesn't make good business sense."
However, Flag Kit says it only sells the flag for educational purposes and asks customers why they want the flag before selling.
There clearly is a market for the old flag - the Facebook group Oranje Blanje Blou has more than 19 000 members dedicated to bringing the old flag back into fashion.
And as Flag Kit sells most of its products online, it is hard to stop flags of the apartheid era ending up in the public arena.
Recently, political commentator Khaya Dlanga called for the old South African flag to be banned, a suggestion that has been both strongly supported and heavily criticised.
Technically, anyone who wants to produce the old South African flag needs permission from the president.
