Overnight lines, packed shopping centres and stock that sells out in minutes.

These toothy little collectible monsters are Labubus, and they have become an unlikely status symbol.

The fluffy figurines are inspired by Nordic folklore, the brainchild of artist Kasing Lung.

But when you buy one, you don’t know exactly what you’re getting until it’s out of the box.

A single Labubu will set you back anywhere from around $30 to over $85. They go for even more on resale sites.

And last year alone, Chinese toy-maker Pop Mart made more than $1 billion from the dolls.

The dolls were first launched in 2015, but it wasn’t until Lisa from K-pop band Blackpink started raving about Labubus that the mania really took off.

So is the Labubu craze here to stay - or will they all end up in the Labinbin?

A Pop Mart spokesperson told news.com.au, “This isn’t just about ‘toys’ but a collectable, pop-culture movement engaging Australian adults like never before.”

“The excitement here mirrors what we’ve seen in major cities globally, with queues forming around the block as eager collectors hope to get their hands on these unique pieces.

“We collaborate with a series of designers to create highly collectable figurines, and the range has grown from strength to strength.”

People have even been been offering to pay strangers $100 to line up in the long queues, in the hopes of buying one of these blind box toys.
