Novelty soap and chocolate makers should be overjoyed - a new mould set has gone up for sale on Trade Me, and the seller reckons they're the only ones in the country.
Diane Callanan designed the moulds herself, modelled by a man, and created 10 identical ones around 20 years ago.
She says so far, they've only been used to create soap - but they could be used to make penis-shaped candies.
"I never actually got around to making chocolate," Ms Callanan says.
Part of the issue is the size of them - "quite big", which means it takes a fair amount of chocolate to fill up.
It got too expensive, so Ms Callanan stuck to soap.
Twenty years ago, sex parties were quite popular, she says - which is why these unique moulds were created.
But since then they've petered out.
"That rage has gone - people aren't going to sex parties anymore," Ms Callanan says.
She hopes they'll sell to someone who'll see the novelty factor in the moulds.
"Whoever gets it, gets it."
