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.
