A children’s coin kit sold by the Royal Australian Mint has been recalled after safety concerns emerged over its plastic case, with the consumer watchdog warning buyers to stop using it immediately and keep it away from children.

The recall affects the Mint’s $30 Tooth Fairy Kit, which went on sale earlier this year and included an uncirculated $2 coin, a plastic case, a toothbrush and a tooth chart.

Marketed as a keepsake for children, the product had been described as “specially crafted” to “capture the magic of the Tooth Fairy’s visit”.

But the Australian Competition and Consumer Commission (ACCC) said the plastic case was found to be emitting a “strong chemical odour” that could cause “irritation or injury” if inhaled.

“Stop using the product immediately and keep out of reach of children,” the ACCC warned.

The kits were sold between February 28 and March 31 through the Royal Australian Mint, Adelaide Exchange, Peter’s of Kensington, Peter Strich Stamps & Coins, and Swan Bullion as well as online.

Buyers unsure whether their purchase is affected are told to check for barcode number 9314688 11923 9 or product code 11923.

Customers can return the kit to the retailer where it was bought for a full refund or a replacement.

The Mint said buyers could keep the coin itself but should return the case and other components for a partial refund.
