Kazzie Mahina of Byron Bay said she never dreamed her creations would be selling out of Sydney stores before even being stocked and topping multiple online lists as the No. 1 Christmas toy for girls under the age of 15, The (Sydney) Daily Telegraph reported Friday.
"People laughed at me 10 years ago when I started. But it was my dream and I kept at it," she said.
Mahina said the fins have passed muster with water safety experts.
"They were developed to inspire the hearts, imagination and dreams of children," she said.
