A seemingly harmless plastic ball with colourful rubber knobs and a simple device that you flick to trigger a spin are among the toys that have been recalled from shelves because of the danger they pose to young children.

Last December, Toys 'R' Us Singapore issued a voluntary recall of Bruin Wiggle Ball toys because their rubber knobs and plastic backs can detach, posing a choking hazard to children. And remember the fidget spinner that became a worldwide craze last year? Some models were taken off the shelves in Britain because they were found to have small parts that could pop out easily, also posing a choking hazard.
